Data Grid Nested Headers

This section will discuss how to create spreadsheets with nested headers and how to modify them programmatically.

Documentation

Methods

You can use the following methods to update the nested headers programmatically:

Method	Description
getNestedCell(number,number)	Get a nested header cell (DOM element). `getNestedCell(x: Number, y: Number) : DOMElement`
setNestedCell(number,number,object)	Define the nested header cell attributes @param {Number} x - coordinate x @param {Number} y - coordinate y @param {Object} properties - Possible attributes: { title: String, align: String, colspan: Number, tooltip: String, frozen: Boolean } `setNestedCell(x: Number, y: Number, properties: Object) : void`
setNestedCell(object[])	Define the nested header cell attributes @param {Object[]} updates - array of objects { x,y,properties } `setNestedCell(updates: Number\|Object[]) : void`
getNestedHeaders	Return the nested header definitions. `getNestedHeaders() : []`
setNestedHeaders(array)	Set the nested header definitions. `setNestedHeaders(config: []) : void`
resetNestedHeaders()	Reset the nested header definitions. `resetNestedHeaders() : void`

Initial Settings

Learn how to generate a new spreadsheet containing nested headers.

Property	Description
nestedHeaders: array of items	Worksheet nested header definitions. Possible attributes: { title: String, colspan: Number, tooltip: String, frozen: Boolean }

Available Events

Event	Description
onchangenested	When changing the nested headers definitions `onchangenested(worksheet: Object, config: Object) : void`
onchangeheadercell	Update the properties of a nested header cell. `onchangeheadercell(worksheet: Object, positionXOrArrayOfUpdates: Number\|Object[], positionY?: Number, config?: Object) : void`

Examples

Nested header example

The following example demonstrates a basic configuration for nested headers in the JSS spreadsheet. See a working example of a JSS spreadsheet with nested headers that updates programmatically on JSFiddle.
