[Suggestion] Table Coloring

[Bassiliya]

So, I've been making wiki-style tables in BBCode for roleplay reasons. Something that I've noticed is that NS BBCode for tables is lacking in a few ways, especially when it comes to background colors for cells. Perhaps the BBCode NS uses could reflect general BBCode usage for coloring cells, like how other sites use "bg" to denote background color. For example, [td bg=red]Text[/td] could make that cell's background color red. Right now, the best alternative is using [background-block], which is a sadly lacking solution. See examples down below:

Idea of what I'm looking for:

Taken from the List of Prime Ministers of the United Kingdom Wikipedia page

The sad example of what [background-block] gives:

It only partially fills the cell and if you have a tall row height, it looks even worse since it covers even less of the cell.

This would be nice!
