title: Bound cell formula to a sorted table
body: <p>I have a table at <code>A1:C5</code> and also formula at <code>H50</code> <code>=C1+C2</code> and <code>H51</code> <code>=C3+C4+C5</code></p>
  <p>How can I sort the table by column <code>B</code> without messing up <code>H50</code> and <code>H51</code>? (I want that the formulas will be 'bound' to the cells even if the row position is changing)</p>
  <p>Thanks.</p>
