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
}
