Tables with that X configuration as seen in plan tend to wobble side to side significantly (torsion) if it's used for such as dining tables. It's less noticeable in smaller tables, e.g., coffee tables with their shorter legs and generally shorter span of the rails. I mention this disadvantage because it's not obvious what size your plans for a table might be from your sketch.
For the most part, with exceptions, I wouldn't use this configuration for a dining table because the torsioning (rotation) can be severe enough to cause liquid spillage from drinking vessels, e.g., cups, mugs, wine glasses, etc. Slainte.
