Node cli table

Package Exports

  • tty-table
  • tty-table/adapters/automattic-cli-table

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tty-table) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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.
Use this.style within function body to style text, i.e. this.style("mytext", "bold", "green", "underline").
Please note that fat arrow functions () => {} don't support scope overrides, and this feature won't work within them. For a full list of options, see: kleur.
headerAlign string default: "center"
headerColor string default: terminal's default color
marginLeft integer default: 0
marginTop integer default: 0
width string || integer default: "auto"
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

Example

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) ? this.style(str, "green", "bold") : 
      this.style(str, "red", "underline")
  }
}]


rows array

Example

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


  • Footer is optional

Example

const footer = [
  "TOTAL",
  function (cellValue, columnIndex, rowIndex, rowData) {
    let total = rowData.reduce((prev, curr) => {
      return prev + curr[1]
    }, 0)
    .toFixed(2)

    return this.style(`$${total}`, "italic")
  }
]


options object

Param Type Description
borderStyle string default: "solid". "solid", "dashed", "none"
borderColor string default: terminal default color
color string default: terminal default color
compact boolean default: false Removes horizontal lines 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:
"truncate":"..."
the cell will be truncated with "..."

Example

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