How can we get over the limits in Excel?

Hi

I have a large assy here with 30 or so configs. I want to drive them via a design table. The problem is that excel is limited to 256 columns and I want a few more.

Can I spill these over onto a second sheet somehow? or should I break the assy done into subs, each having a design table of their own and nest things upwards?

Thanks

Darren
