Table. Any table from a kitchen to a multi thousand dollar studio shooting table will do. Let's use a kitchen table! Set it up against the wall so the wall forms a backdrop or a surface where you can tape a cloth or paper backdrop. You can get all kinds of paper including a roll of wallpaper to drape down the wall and over the table. There are some really nice designs available which make excellent backdrops. They are also quite cheap and 'disposable'. If you need something more durable than paper why not pop over to the local fabric store and see what they have. I found some vynal and in some nice colors too. Fabric usually comes in 52" widths so it should cover the biggest table you'll use. I find fabric to be better to use due to the width, wallpaper is only 20 1/2" wide and restrictes what you can shoot or how far away you can shoot if you are filling the frame with the backdrop. I would suggest you buy 2 colors to start with, Black and White. If you do buy black, I have found that Black Velvet is the best to buy. It absorbs light rather than reflect it back at the camera producing flare. Beware: it's not cheap!
Light. Lights come in all shapes sizes and power levels, from a simple 3 watt stick on lamp to a multi thousand dollar studio flash system. Through practice I have found that for casual tabletop photography a simple desk swingarm lamp produces excellent results. Most of us own at least one of these already! If you don't, 10-15 bucks should cover it. They are really handy to use, just clamp it to the side of the table, point it at the subject and start shooting basically. A 60 or 100 watt bulb is plenty of light for tabletop photography! Want more? Buy another lamp. It's that simple.
One other thing to consider is that Aperture Prefered Mode should be chosen as Depth Of Field is now the main consideration.
Handy accessories.
You should consider buying a Tabletop Tripod. This is a mini tripod maybe only several inches high and you just set it up on the table. As shutter speeds will be somewhat slow, this should be on your list to buy. They range in price from about 12 - 40 bucks. Just buy one that will support your camera.
If you get more interested in tabletop photography you could go to Lowes or Home Depot and get a utility ottoman size white box. They make excellent shooting booth's. If you go this route I suggest buying a strip light to screw onto the underside of the top to provide the lighting. I have had a great deal of success using a 13 watt striplight.
Pop over to your local art supply store and pick up some pieces of white foam core. That is "Card/foam/card sandwich material and you can cut it to what ever size you want with a knife. Normally it comes in 1/8th thick or 1/4" thick sizes. This material makes excellent reflector boards. Cut some pieces ranging from 3x3 up to 12x12 in size and you can use them to reflect light back into the shadow area's of your subject. Propping them up is where you get "inventive" lol.
Have fun!
