If this is a fixed gantry design then I would go ahead and put in the
stiffeners. On a small table of 13 X 26 2" square tubing is pretty
strong unless you plan on mounting a mongo router and cutting 3/4
solid oak in one pass! Do you have gussets at the top 45 corners
welded to the outside?

If it's a moving gantry then weight starts to become an issue and
bracing should be added only where necessary.
