Not everyone will have the current Xara Pro+ capability to work with the integrated Table Tool but many can still create such tables from the Online Content Catalogue and so can join in these Challenges.
The approaches will be different but skills developed will be transferrable so not wasted.

Challenge 0 is to create 1x1 square Cell table of side 100px.
The point of this is to show Xara now has a Tool that allows precise construction.

The main challenge is to discover the simplest approach or shape that allows you to produce coloured cell patterns be they chessboard or zebra striping:

Create a modestly sized Table - mine is 17x6 - make your big enough so you don't just select groups of Cells and colour.
In other words, can your solution scale?

Challenge 1 - Recreate the colouring for the Tables with Green/White Cells.

This challenge is not simple for earlier XDA versions for the Chessboard patterning.
