code: func (l *State) Table(index int) {
  	l.stack[l.top-1] = l.tableAt(l.indexToValue(index), l.stack[l.top-1])
  }
docs: // Table pushes onto the stack the value table[top], where table is the
  // value at index, and top is the value at the top of the stack. This
  // function pops the key from the stack, putting the resulting value in its
  // place.  As in Lua, this function may trigger a metamethod for the __index
  // event.
