CellSelection

The CellSelection mixin extends upon the functionality of the Selection mixin to provide selection at the cell level instead.

require([
    "dojo/_base/declare", "dgrid/OnDemandGrid", "dgrid/CellSelection"
], function(declare, OnDemandGrid, CellSelection){
    var grid = new (declare([OnDemandGrid, CellSelection]))({
        selectionMode: "single",
        // ...
    });
});

Differences from Selection mixin

• The selection object stores a nested hash, where the outer hash is keyed by item ID and the inner hashes are keyed by column ID.
• The dgrid-select and dgrid-deselect events still fire, but include a cells property containing an array of cell objects, rather than a rows property.
• Whereas Selection's select, deselect, and isSelected methods look up the passed argument via List's row method, CellSelection looks it up via Grid's cell method.
• The allowSelect method is passed a cell object instead of a row object.
