I bring an extra column in my result array just for some meta data about the row to enable drilldown but i dont want that column to be rendered. how should i hide it? i have tried using columns =>array(
.......,"selectedcolumn"=>array("visible"=>false)
)
but it doesnt work.
Or is there a better way to pass meta-data for a column which is only used for hidden purposes like click events because even if you hide columns , it will leave vacant space in the UI.
