There is a missing piece in slat of my rattan table, can I fix it?

I would go to a granite yard and look through the boneyard to find a suitable color. Pay them a small amount just to rough cut to size. I have bought tops like that for about $40 including the cuts. Sit the granite on top of the damaged tabletop. BTW Easier to set drinks and food on than the uneveness of woven wicker.

You could try using a moldable clay or plaster, something like shapecrete, to create the missing individual pieces. You could then paint them to match the rest of the table.

Is there an inconspicuous place underneath or hidden from view in which you can remove and replace in this area?

Karen's idea is great, but if there's no place you can "steal" from, look around for an old basket or chair that has similar size pieces of rattan. Would take some extra care in gluing each piece in place. Then maybe repaint the whole table (or just the diamond section).....

or...

A nice centerpiece would look good sitting there

I have done repairs sinilar to this years ago. Thrift stores always have baskets. Try to find a similar basket to "harvest" from. Soak pieces for patching in hot water to facilitate ease of reweaving in the patch. Touch up with craft paints.

Try using the stems of a tootsie role pop, to weave in, & make a new wicker patch.

Glue from back side, & paint..

What if you soak some cocktail sticks, then whilst wet, slid the sticks using glue and put them in position, once dried match a colour

I remember somewhere you can buy the rattan... you may want to ask around and/or call some likely stores. such as hobby lobby.

How about twine!!

There is a place in Plainwell Michigan that carries supplies for working on wicker and Rattan, I just can't remember the name. Maybe you could Google it.
