columns().nodes()

Since: DataTables 1.10

Get the cell nodes for the selected columns.

Description

This method is used to get the nodes of for the cells (th / td elements) in the columns matched by the selector.

Please note that the order of the nodes in the returned array and which rows the nodes are obtained from (searched rows, visible rows etc) is controlled by the selector-modifier option of the columns() selector used to get the selected columns.

Furthermore, please be aware that using deferRender will cause some nodes to be created only when they are required for display, so they might not be immediately available when this method is called.
