How to specify style for TableLayout?

[dbassett74]

I'd like to apply a style to the actual table of a TableLayout, not the individual panels the result. Specifically, I would like to specify a border to show (for columns and rows as well). Seems by default, the table itself has no border style. Is this possible?

TableLayout has a tableAttrs config option and individual items have a cellCls config option.
