The answer is yes, but there are a few things you need to know first. Jointers are designed to create flat, 90-degree joints between two pieces of wood. This is done by running the wood through the jointer's blades, which cut away any unevenness.
Table saws, on the other hand, are designed for making rip cuts - cuts that are parallel to the grain of the wood. So, while you can use a table saw to create a flat, 90-degree joint, it's not the ideal tool for the job.
