# 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

const container = document.getElementById('example');
const hot = new Handsontable(container, {
  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']
 ],
