slate-deep-table

A Slate plugin to handle tables with nested block content. Forked from the excellent slate-edit-table implementation, but retooled to work with deep content.

Demo: https://jasonphillips.github.io/slate-deep-table/

Install

npm install slate-deep-table

Features

• Pressing Up and Down, move the cursor to next/previous row
• Pressing Tab, move the select to next cell
• Pressing Shift+Tab, move the select to previous cell
• Permits nested block content within table cells
• Optionally create headerless tables

Compatibility

Slate is a fast-moving library, so check the CHANGELOG for information on the currently supported version.

Simple Usage

import DeepTable from 'slate-deep-table'
 
const plugins = [
  DeepTable({ /* options object here; see below */ })
]
 
// now instantiate your Slate Editor with these plugins, according to slate documentation

Options

• [typeTable: String] — type for table default: 'table'
• [typeRow: String] — type for the rows default: 'table_row'
• [typeCell: String] — type for the cells default: 'table_cell'
• [typeContent: String] — type for the default blocks within cells default: 'paragraph'

Queries and Commands

slate-deep-table exports queries and commands that you can invoke on your editor instance:

// anywhere where 'editor' is passed as an argument, or using the react Component's ref, 
// you may directly invoke any of the exported functions below, e.g:
const inATable = editor.isSelectionInTable();
 
if (!inATable) {
  editor.insertTable();
}

Check example/main.js for usage in a typical context.

query isSelectionInTable()

editor.isSelectionInTable() => Boolean

Return true if current cursor position is inside a table.

query getTablePosition()

editor.getTablePosition() => null || TablePosition

Returns null if cursor is not in a table, else returns an object you can use to query the current cell and row location:

const position = editor.getTablePosition()
 
position.getRowIndex() // returns row id (0-indexed)
position.getColumnIndex() // return column index (0-indexed)
position.getWidth() // returns count of columns
position.getHeight() // returns count of rows
