Column Width in DataGrid

Hi,
I’m using a DataGrid to display certain tabular data, except a couple of columns that have buttons in them.
I’ve used CellRenderer API to display those buttons, but when I run the movie, upon resizing the column and making them small, the buttons spill over to the adjoining columns …

Is there anyway to prevent this ?
I want the columns to be resizeable. Is there a minimum Column Width that I can specify ?

Help would be much appreciated :slight_smile:
