Formatting tables can actually be quite complex (and no two people seem to have the same idea of how they want it formatted). Probably your best approach is to create the table you want in something like Word etc. and then grab a screenshot of the table to include as a slide image once you have it all formatted the way you want (that is the way I have done it in the past).
