sortable

- a tiny, vanilla/plain JavaScript table sorter

Makes any table with class="sortable", er, sortable. The user can click on a table header and change the sorting of the table rows.

Just include the JavaScript and it will work. No function calls are needed, everything is handled by an eventListener.

Demo

You can find a simple demo on https://tofsjonas.github.io/sortable/

Table of Contents

Factoids

  • 1180 bytes minified. (617 bytes gzipped)

  • Works with JavaScript generated tables. (since we are using an eventListener)

  • Lightning fast. Huge tables will make it slow and may freeze the browser, especially for mobiles, so you know...

  • Requires thead and tbody.

  • cross browser, ie9+ No longer ie9 compatible. Then again, maybe it already wasn't 🤷

  • NOT tested with React, Angular, Vue, etc.

  • Works with Svelte!

"Installation"

There are three ways to use sortable, all of which have their pros and cons. S Anand and dkhgh had some interesting thoughts about it.

  1. Include a link to jsDelivr. (easiest)

  2. Copy the file from jsDelivr or Github and put it in your assets folder. (in between)

  3. Install the npm package. (most reliable)

1. link to jsDelivr

<table class="sortable">
  <thead>
    <tr>
      <th><span>Role</span></th>
      <th>Name</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Genius</td>
      <td>Rick</td>
    </tr>
    <tr>
      <td><a href="javascript:alert('Inline javascript works!');">Sidekick</a></td>
      <td>Morty</td>
    </tr>
  </tbody>
</table>
<link href="https://cdn.jsdelivr.net/gh/tofsjonas/sortable@latest/sortable.min.css" rel="stylesheet" />
<script src="https://cdn.jsdelivr.net/gh/tofsjonas/sortable@latest/sortable.min.js"></script>

The span on line four is just there to prove that you can have elements inside th!

⚠️ If you are concerned about bugs, I recommend using version numbers instead of "latest".

2. copy file to assets folder

Same as above, but link to your own files

...
<link href="/assets/sortable.min.css" rel="stylesheet" />
<script src="/assets/sortable.min.js"></script>
...

3. npm package

First,

npm install sortable-tablesort
# yarn add sortable-tablesort
# pnpm install sortable-tablesort

Now you can

a) use links in the html

Same as above, with links to files

...
<link href="./node_modules/sortable-tablesort/sortable.min.css" rel="stylesheet" />
<script src="./node_modules/sortable-tablesort/sortable.min.js"></script>
...

or

b) import files in javascript

// main.js
import 'sortable-tablesort/sortable.min.css'
import 'sortable-tablesort/sortable.min.js'

Non-sortable field

...using class="no-sort"

If you wish to disable sorting for a specific field, the easiest (and best) way is to add class="no-sort" to it, like so:

<thead>
  <tr>
    <th class="no-sort">Role</th>
    <th>Name</th>
  </tr>
</thead>

Sorting will not be triggered if you click on "Role".

...using CSS

This is a bit trickier, but it doesn't require any changes to the html, so I guess it could be worth it in some cases.

/* the first column in every sortable table should not be sortable*/
.sortable th:nth-child(1) {
  pointer-events: none;
}

/* the seventh column in the second .sortable table should not be sortable*/
.sortable:nth-of-type(2) th:nth-child(7) {
  pointer-events: none;
}

...using td instead of th

The eventListener only triggers on th, not td, so this would disable sorting for "Role":

<thead>
  <tr>
    <td>Role</td>
    <th>Name</th>
  </tr>
</thead>

⚠️ Since th and td are not the same thing, you would most likely still have to use CSS to make them look the way you want. (It might also mess with accessibility.) In some cases it could be worth it, but I recommend the .no-sort alternative.

Indicators/arrows on the left side

If you have text that is aligned on the right side, you may want to have the arrows on the left side.

This is solved by adding a class to the css and using ::before instead of ::after.

(You can of course use a pure css solution, without class names - just like with the non-sortable field - but that I will leave for you to figure out.)

.sortable th.indicator-left::after {
  content: '';
}
.sortable th.indicator-left::before {
  margin-right: 3px;
  content: '▸';
}
/* etc. */

Full example: CSS, SCSS

NOTE ABOUT CSS/SCSS

The css/scss in this repo was only ever meant as an example. It was never intended to be actually used.

That said, if you're feeling lazy, here are two stylesheets you can use:

<!-- This will add arrows, as well as support for .no-sort and .indicator-left -->
<link href="https://cdn.jsdelivr.net/gh/tofsjonas/sortable@latest/sortable-base.min.css" rel="stylesheet" />

<!-- This will make it look like the tables in the example, with arrows, striped rows etc. -->
<link href="https://cdn.jsdelivr.net/gh/tofsjonas/sortable@latest/sortable.min.css" rel="stylesheet" />

Sorting sizes, dates and such

Using the data-sort attribute in tbody > td you can have one visible value and one sortable value. This is useful in case you have for instance sizes like kb, Mb, GB, or really weird date formats. 😉

<table class="sortable">
  <thead>
    <tr>
      <th>Movie Name</th>
      <th>Size</th>
      <th>Release date</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Zack Snyder's Justice League</td>
      <td data-sort="943718400">900MB</td>
      <td data-sort="20210318">03/18/2021</td>
    </tr>
    <tr>
      <td>The Sound of Music</td>
      <td data-sort="1610612736">1.5GB</td>
      <td data-sort="19651209">12/09/1965</td>
    </tr>
  </tbody>
</table>

Alternative sorting

If you click on a table header while holding shift or alt an alternative data-sort-alt attribute will override data-sort.

<table class="sortable">
  <thead>
    <tr>
      <th>Movie Name</th>
      <th>Size</th>
      <th>Release date</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Something</td>
      <td data-sort-alt="c" data-sort="a">A</td>
      <td data-sort-alt="b" data-sort="c">B</td>
      <td data-sort-alt="a" data-sort="b">C</td>
    </tr>
    <tr>
      <td>Something else</td>
      <td data-sort-alt="e" data-sort="f">D</td>
      <td data-sort-alt="f" data-sort="e">E</td>
      <td data-sort-alt="d" data-sort="d">F</td>
    </tr>
  </tbody>
</table>

Colspans/Sort on specific column

Using the data-sort-col attribute in thead > th, you can sort on a different column than the one that was clicked. For instance if you want to have colspans. Like so:

<thead>
  <tr>
    <th></th>
    <th>Category</th>
    <th class="show_name">Show</th>
    <th colspan="2">Overall</th>
    <th colspan="2" data-sort-col="5">On Our Dates</th>
    <th data-sort-col="7">First Sold Out</th>
  </tr>
</thead>
<tbody>
  <tr>
    <td class="tags">&nbsp;</td>
    <td class="category">Comedy</td>
    <td class="show_name">Show 1</td>
    <td class="ratio all" data-sort="72">18/25</td>
    <td class="pct all">72%</td>
    <td class="ratio ours" data-sort="75">3/4</td>
    <td class="pct ours">75%</td>
    <td>2022-07-30</td>
  </tr>
  ...
</tbody>

Ascending sort

By adding asc to table, the default sorting direction will be ascending instead of descending

<table class="sortable asc">
  <thead>
    ...
  </thead>
  <tbody>
    ...
  </tbody>
</table>

Tiebreaker / secondary sort

If you wish to sort by a different column when two values are equal, you can use the data-sort-tbr attribute, like so:

<table class="sortable asc">
  <thead>
    <tr>
      <th data-sort-tbr="1">Year</th>
      <th>Month</th>
      <th>Day</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>2010</td>
      <td>07</td>
      <td>25</td>
    </tr>
    <tr>
      <td>2010</td>
      <td>11</td>
      <td>12</td>
    </tr>
    <tr>
      <td>2010</td>
      <td>04</td>
      <td>25</td>
    </tr>
  </tbody>
</table>

When clicking Year, if they are the same, we will sort on Month.

Empty/null rows always last

Adding class="n-last" to <table class="sortable"> will make empty/null values always be sorted last, similar to what SQL does with ORDER BY foo NULLS LAST.

<table class="sortable n-last">
  <thead>
    <tr>
      <th>Text</th>
      <th class="indicator-left">Number</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>jkl</td>
      <td>0.4</td>
    </tr>
    <tr>
      <td>This will always be sorted after the others</td>
      <td></td>
    </tr>
    <tr>
      <td>abc</td>
      <td>0</td>
    </tr>
    <tr>
      <td>def</td>
      <td>0.2</td>
    </tr>
  </tbody>
</table>

⚠️ Note that a string of blank spaces is not considered null/empty. <td data-sort=" "></td> will be sorted normally.

Accessibility

Sortable is not very accessible in its raw form. It does not support screen readers, and it does not have any keyboard support. Including sortable.a11y.min.js in your project will add some basic accessibility features.

<table class="sortable">
  ...
</table>
<link href="sortable.min.css" rel="stylesheet" />
<script src="sortable.min.js"></script>
<script src="sortable.a11y.min.js"></script>

By including the file the global function enhanceSortableAccessibility will automatically run through all existing .sortable tables, but you can also run it manually, like so:

enhanceSortableAccessibility([table1, table2,...etc.])

The function adds an aria-label to each th, as well as tabindex="0" to each th in the thead of each table, making it possible to tab through the headers. It updates the aria-label depending on the direction.

if you want to import it instead this should work: (I haven't tested it)

import { enhanceSortableAccessibility } from 'sortable-tablesort/enhanceSortableAccessibility'
enhanceSortableAccessibility([table1, table2,...etc.])

Sort on load

If you wish to sort a table on load, I would recommend doing something like this:

<table class="sortable">
  <thead>
    <tr>
      <th>Movie Name</th>
      <th id="movie-size">Size</th>
      <th>Release date</th>
    </tr>
  </thead>
  <tbody>
    ...
  </tbody>
</table>

<script>
  window.addEventListener('load', function () {
    const el = document.getElementById('movie-size')
    // without id:
    // const el = document.querySelector('.sortable th:first-child')
    // const el = document.querySelector('.sortable th:nth-child(2)')
    // const el = document.querySelectorAll('.sortable')[3].querySelector('th:nth-child(7)')
    // etc.
    if (el) {
      el.click()
    }
  })
</script>

Combine this with <table class="sortable asc"> to reverse the sort order. Or do el.click() twice!
