Forum:Wikitables - what is the default colour are the cells?

What colour are the cells in tables like these? Or does it depend on the browser? I know on cerain browsers columns 2 and 3 are hardly visible (partly I guess depending on monitor settings), while others will actually still show a line at the end of the final column to close the table. But if I wanted to hide some of the grid lines, what colour hexcode should I make them to make them least likely to be visible, as I suspect white is not the best choice?

I think its transparent, but this can be changed for a color or picture by coding. Stevenator Sand
