    API Reference

    Table(header array, rows array, options object)

    Param Type Description
    header array Per-column configuration. An array of objects, one object for each column. Each object contains properties you can use to configure that particular column. See available properties
    rows array Your data. An array of arrays or objects. See examples
    options object Global table configuration. See available properties

    header array of objects

    Param Type Description
    alias string Text to display in column header cell
    align string default: "center"
    color string default: terminal default color
    footerAlign string default: "center"
    footerColor string default: terminal default color
    formatter function(cellValue, columnIndex, rowIndex, rowData, inputData Runs a callback on each cell value in the parent column.
    Please note that fat arrow functions () => {} don't support scope overrides, and this feature won't work correctly within them.
    @formatter configure function(object) Configure cell properties. For example:
    this.configure({ truncate: false, align: "left" }) More here.
    @formatter resetStyle function(cellValue) Removes ANSI escape sequences. For example:
    this.resetStyle("[32m myText[39m") // "myText"
    @formatter style function(cellValue, effect) Style cell value. For example:"mytext", "bold", "green", "underline")
    For a full list of options in the terminal: chalk. For a full list of options in the browser: kleur
    headerAlign string default: "center"
    headerColor string default: terminal's default color
    marginLeft integer default: 0
    marginTop integer default: 0
    paddingBottom integer default: 0
    paddingLeft integer default: 1
    paddingRight integer default: 1
    paddingTop integer default: 0
    value string Name of the property to display in each cell when data passed as an array of objects
    width string || integer default: "auto"
    Can be a percentage of table width i.e. "20%" or a fixed number of columns i.e. "20".
    When set to the default ("auto"), the column widths are made proportionate by the longest value in each column.
    Note: Percentage columns and fixed value colums not intended to be mixed in the same table.


    let header = [{
      value: "item",
      headerColor: "cyan",
      color: "white",
      align: "left",
      width: 20
      value: "price",
      color: "red",
      width: 10,
      formatter: function (value) {
        let str = `$${value.toFixed(2)}`
        return (value > 5) ?, "green", "bold") : 
, "red", "underline")

    rows array


    • each row an array
    const rows = [
    • each row an object
    const rows = [
        item: "hamburger",
        price: 2.50

    footer array

    • Footer is optional


    const footer = [
      function (cellValue, columnIndex, rowIndex, rowData) {
        let total = rowData.reduce((prev, curr) => {
          return prev + curr[1]
        }, 0)
        return`$${total}`, "italic")

    options object

    Param Type Description
    borderStyle string default: "solid".
    options: "solid", "dashed", "none"
    borderColor string default: terminal default color
    color string default: terminal default color
    compact boolean default: false
    Removes horizontal borders when true.
    defaultErrorValue mixed default: '�'
    defaultValue mixed default: '?'
    errorOnNull boolean default: false
    truncate mixed default: false
    When this property is set to a string, cell contents will be truncated by that string instead of wrapped when they extend beyond of the width of the cell.
    For example if:
    the cell will be truncated with "..."
    Note: tty-table wraps overflowing cell text into multiple lines by default, so you would likely only utilize truncate for extremely long values.
    width string default: "100%"
    Width of the table. Can be a percentage of i.e. "50%" or a fixed number of columns in the terminal viewport i.e. "100".
    Note: When you use a percentage, your table will be "responsive".


    const options = {
      borderStyle: "solid",
      borderColor: "blue",
      headerAlign: "center",
      align: "left",
      color: "white",
      truncate: "...",
      width: "90%"
