Why does the Column Layout Grid for Product Listing uses "DIV" tag to measure products? Why did not drbyte (there's his name in the header of tpl_columnar_display.php) use the "TABLE" for this purpose?
Is "div" just a preferred tag, or there are some logical reasons to use it?

This question appeared with issue to add some free space between products on products listing page after installing "product listing pages with column layout grid" contribution using "margin" or "padding" in CSS. I thought, it could be easily done if there was a table instead of div.
The other issue was to make border on every product "box". Every div tag has it's own height, so it's possible to just add "border" in CSS for it.
