columns.orderSequence

Order direction application sequence.

Description

You can control the default ordering direction, and even alter the behaviour of the order handler (i.e. only allow ascending sorting, reverse the default sequence, etc) using this parameter.

Values that can be given in this array are:

• asc - Ascending order
• desc - Descending order
• (i.e. empty string) - data index order. Note that this option is available as of DataTables 2.0 and newer.

Prior to DataTables 2 this option defaulted to [ 'asc', 'desc' ]. DataTables 2 added the third option to the array with the empty string included in the default for the no sort state. If you would like to use the DataTables 1.x behaviour, set the default using:

DataTable.defaults.column.orderSequence = ['asc', 'desc'];

Type

This option can be given in the following type(s):

• array

Default

• Value: [ 'asc', 'desc', '' ]

Examples

new DataTable('#myTable', {
	columnDefs: [
		{ orderSequence: ['asc'], targets: [1] },
		{ orderSequence: ['desc', 'asc', 'asc'], targets: [2] },
		{ orderSequence: ['desc'], targets: [3] }
	]
});

new DataTable('#myTable', {
	columns: [
		null,
		{ orderSequence: ['asc'] },
		{ orderSequence: ['desc', 'asc', ''] },
		{ orderSequence: ['desc'] },
		null
	]
});
