Hi!

There are no way without subclassing.

For what you need this functionality??? MANY things for grid could be done quite another way than just subclassing columns. I worked on the grid that do very complex processing for ALL columns in grid, but nether worked so slow even for grids with 200 columns.

I can also look to code and tell what could be improved and how to improve speed.
