# Custom Sorting

Sometimes you may wish to override the default sorting logic which is applied uniformly to all columns.

To do so use the `customSorting` option. This is an object that recieves custom logic for specific columns.

E.g, to sort the `name` column by the last character:

name: function (ascending) {

var lastA = a.name\[a.name.length - 1].toLowerCase();

var lastB = b.name\[b.name.length - 1].toLowerCase();

return lastA >= lastB ? 1 : -1;

return lastA <= lastB ? 1 : -1;

This depends entirely on your backend implemetation as the library sends the sorting directions through the request.
