How to disable column in Grid

[somu_ngm]

Hai All!
I have one doubt in my hand and i want to share it to u all my dear friends.

that is,
How to disable one column in grid.Grid may contains several columns in it.Now i want to disable some columns only(Note: dont disable all column here).

we can easily disable all columns in grid using enabled or editable attribute og grid tag.

Note: i want disable particular column of grid in dynamically that is do it from script not from tag directly.

thanks
