Add css class to columns in grid!

When I define grid, each column must be declare width and align.

mygrid.setInitWidths("100,120,110,120"); mygrid.setColAlign("center,center,left,left");
I want add class to column, when I modify class, width and align of columns will change. How to do it? Thanks so much!

Unfortunately it’s not available to add the css class for an individual column of the grid.
