The problem is that a member function has an extra, implicit parameter, the object
whose member function is being called. "this".

Depends on how involved in C++ arcana you want to be. ;-)
Simple, non C++ solution:
Use a global
TableObject *theTable;
void MyTableDrawItemFunc (void *tableP, Int16 row, Int16 column, RectangleType *bounds)
{ theTable->TableDrawItem ( tableP, column, bounds ); }
.... in your code somewhere ....
theTable = &<your table object>;
TblSetCustomDrawProcedure ( tableP, column, MyTableDrawItemFunc );
A better solution is to package the object pointer and the function into an object
that does this all automatically. This is called a 'functor' in C++ lingo.
Unfortunately, the table draw dispatcher doesn't know C++ from
anything, so it can't use operator () to get a function pointer.
