React Data Grid NestedHeaders

Description

The plugin allows to create a nested header structure, using the HTML's colspan attribute.

To make any header wider (covering multiple table columns), it's corresponding configuration array element should be provided as an object with label and colspan properties. The label property defines the header's label, while the colspan property defines a number of columns that the header should cover.

Note that the plugin supports a nested structure, which means, any header cannot be wider than it's "parent". In other words, headers cannot overlap each other.

Example

<HotTable
  data={getData()}
  nestedHeaders={[
    ['A', {label: 'B', colspan: 8}, 'C'],
    ['D', {label: 'E', colspan: 4}, {label: 'F', colspan: 4}, 'G'],
    ['H', {label: 'I', colspan: 2}, {label: 'J', colspan: 2}, {label: 'K', colspan: 2}, {label: 'L', colspan: 2}, 'M'],
    ['N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W']
 ]}
/>

Options

nestedHeaders

Source code (opens new window)

nestedHeaders.nestedHeaders : boolean | Array<Array>

The nestedHeaders option configures the NestedHeaders plugin.

You can set the nestedHeaders option to one of the following:

Setting Description
false (default) Disable the NestedHeaders plugin
true - Enable the NestedHeaders plugin
- Don't configure any nested headers
Array of arrays - Enable the NestedHeaders plugin
- Configure headers that are nested on Handsontable's initialization

If you set the nestedHeaders option to an array of arrays, each array configures one set of nested headers.

Each array element configures one header, and can be one of the following:

Array element Description
A string The header's label
An object Properties:
label (string): the header's label
colspan (integer): the column width
