How to stop a table from wobbling at home.
Either buy or use an old drink coaster. Test out and see which leg is shortest.  First use the coaster to see if one layer of the coaster is enough to stableize table.  If it is go to the next step.  If it isn't repeat with an additional coaster.  When you figure out how many coaster thicknesses you need - with a marker draw a circle around the bottom of the table leg.  Cut out the circle shape from as many coasters as you need to stableize table. Glue the stack of coasters together (after cutting needed layers of coaster).  Glue those to the table leg.  Then you are set.  Repeat on any additional leg that is uneven.
