Simple question about tables

Simple question about tables

I have a simple, silly question. Should I be using GRIDS instead of TABLES for JQueryMobile? I can't find much in the way of support or documentation regarding tables. I'm having really simple problems, like tables being cut off because they're too big for the viewing window. I tried adding a style="font-size:small" to shrink the table, but this didn't work. It seems like the new reflow and column toggles support the idea of tables... What am I missing?
