Shade an entire row or column in a table on a whiteboard

What is the challenge?

Shaded columns and rows help the user visible see what is a header versus what are cells/data. Currently you can shade table rows/columns in the text editor, but you cannot do so in Whiteboards.

What is the impact?

You have to either change the color of each cell, or added a shaded box over the row/column and send the box to the back.

Describe your idea
