Now you can export selected rows and columns at runtime. This means no code change, Export selection options are now on accessible with grid operations toolbar.

Demo: http://phpgrid.org/demo/demos/export/export-selected.php

In demo, select columns using column chooser and rows by multiselect option, then click Export selected button. This will export PDF of selected rows/cols. As the grid exports PDF format, the data table can be printed by your favorite PDF reader.
