Format multiple table cells at once and keep formatting when adding rows or columns

When building tables in the Knowledge Base editor, formatting has to be redone on new rows/columns. We would like to see two improvements.

1. Set background color for a group of selected cells at once. Color can be applied to the whole table, a single row, or a single column, but not to a custom selection of cells, so coloring several rows means repeating the steps for each one.

2. Keep formatting when adding rows and columns. A new row or column comes in with the default font size and alignment instead of matching the row or column next to it, so the formatting has to be reapplied every time the table grows.

Together these would make larger tables much faster to build and maintain.
