How to enable and disable columns fields within a table

Hello all,

I have the following situation,

I need to build a table who has an check box. If i check it, i must to enable and disable (depends of the case) some columns fields of my table´s line. I´ve search some forums thread and i know that this code must be develop on wdmodify view method. But i wonder if you guys have some sample codes or maybe a Weblog link that could help me to solve this problem.

Thank you in advance,

Mariana
