lua_rawseti(L, -2, j);

That'll set the item on the top of the stack (CT) to index j of the table at -2 (RT).

lua_newtable( L ); // push a Row Table (the main table) onto the stack for ( int j = 1; j <= nRows; j++ ) { lua_newtable( L ); // push a Column Table onto the stack for ( int i = 1; i <= nCols; i++ ) { lua_pushnumber( L, i ); lua_pushstring( L, sValue ); lua_settable( L, -3 ); }

lua_rawseti(L, -2, j); // RT[j] = CT }
