Many table saws can be purchased with optional extension wings. Table extension wings bolt on to the right and left sides of the table and increase the surface area of the saw to help support wide stock and sheet materials. On a heavy duty stationary saw, the extensions are usually cast iron, while on smaller saws, they may be made of lighter stamped steel or the lighter "webbed" style of cast iron.
Most table saw trunnions are made to tilt either left or right (but not both) to a maximum of 45 degrees from vertical. If you have a choice, and you usually do, never buy a right-tilt saw for the following reason. A right-tilt saw tilts the blade towards the fence and can pinch a work piece into the fence, causing a jam or, worse, a kickback just as the cut is finishing. Further, on a right-tilt saw, the blade is tilting towards the fence and could cut into and ruin it if the fence were to be inadvertently moved too close to the spinning blade. A left-tilt saw tilts away from the fence and instead of pinching the work piece, allows it to rise vertically slightly, if need be.
Some shops are small enough to require that all machines be able to roll around on the floor. The theory is that you pull out only the machine you are using at the time. In planning your shop, you should decide if your space requirements will mean that everything has to roll, some machines but not others have to roll or all machines can remain in their own positions permanently. Many cabinet saws offer the optional extra of some sort of mobility device. In the case of a table saw, you don't want it rolling around while you are pushing lumber through it and so the wheels must retract enabling the saw to rest on its cabinet base on the floor.
Your new saw must have a rip capacity equal or wider than the widest thing you will ever want to rip. Usually, a cabinet saw will have a rip capacity of around 30 inches or 50 inches. A large rip capacity to the right of the blade will require an extension table to support work wider than the cast iron table. Many times, this extension table is included with the saw or, alternatively, you can easily build you own. The fence must have a tube or rail long enough to achieve the maximum with you want to rip.
The motor, trunnions, arbor assembly, and gearing make up the essential mechanical components of the saw. These quality and robustness of these components varies considerably and can greatly impact the durability of the saw, its capacity for cutting heavy stock and its ability to stay in adjustment and hold settings.
