This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Because you set the min and max sizes to the same value.
Before you hide your column, save the initial min and max, then when you restore your column reset the min and max to what you save. If you don't want to save the values, try setting min to 0 and max to Integer.MAX_VALUE.
I have a bunch of code for sizing, hiding, restoring, and persisting table column information. If you want I'll email it to you.
