JavaScript Data Grid CustomBorders

Table of contents

Description

This plugin enables an option to apply custom borders through the context menu (configurable with context menu key borders).

To initialize Handsontable with predefined custom borders, provide cell coordinates and border styles in a form of an array.

See customBorders configuration option or go to Custom cell borders demo for more examples.

Example

customBorders: [
  {
   range: {
     from: {
       row: 1,
       col: 1
     },
     to: {
       row: 3,
       col: 4
     },
   },
   start: {},
   end: {},
   top: {},
   bottom: {},
  },
],

// or
customBorders: [
  { row: 2,
    col: 2,
    start: {
      width: 2,
      color: 'red',
    },
    end: {
      width: 1,
      color: 'green',
    },
    top: '',
    bottom: '',
  }
],

Options

The customBorders option configures the CustomBorders plugin.

To enable the CustomBorders plugin (and add its menu items to the context menu), set the customBorders option to true.

To enable the CustomBorders plugin and add a predefined border around a particular cell, set the customBorders option to an array of objects. Each object represents a border configuration for one cell, and has the following properties:

Property Sub-properties Types Description
row - row: Number The cell's row coordinate.
col - col: Number The cell's column coordinate.
start width
color		 width: Number
color: String		 If the layout direction is LTR (default): start sets the width (width) and color (color) of the left-hand border.

If the layout direction is RTL: start sets the width (width) and color (color) of the right-hand border.
end width
color		 width: Number
color: String		 If the layout direction is LTR (default): end sets the width (width) and color (color) of the right-hand border.

If the layout direction is RTL: end sets the width (width) and color (color) of the left-hand border.

color		 width: Number
color: String		 Sets the width (width) and color (color) of the top border.
bottom width
color		 width: Number
color: String		 Sets the width (width) and color (color) of the bottom border.

To enable the CustomBorders plugin and add a predefined border around a range of cells, set the customBorders option to an array of objects. Each object represents a border configuration for a single range of cells, and has the following properties:

Property Sub-properties Types Description
range from {row, col}
to {row, col}		 from: Object
to: Object
row: Number
col: Number		 If the layout direction is LTR (default):
- from selects the range's top-left corner.
- to selects the range's bottom-right corner.

If the layout direction is RTL:
- from selects the range's top-right corner.
- to selects the range's bottom-left corner.
start width
color		 width: Number
color: String		 If the layout direction is LTR (default): start sets the width (width) and color (color) of the left-hand border.

If the layout direction is RTL: start sets the width (width) and color (color) of the right-hand border.
end width
