Unless the table was designed specifically for that purpose like the Camco reviewed above, then no. Even the best folding camping tables will wither under the intense heat generated by a gas or charcoal grill unless they’re engineered to deal with it. While it may be tempting to place your gas grill on top of your camping picnic table you should resist that temptation if there is even a tiny bit of doubt about whether your camping table is built to host a grill. Because if it’s not, and you place the grill on it anyway, the tabletop is likely to warp which could lead to a serious accident.
