title: Adding new data in excel and cannot be sorted or filtered
body: <p>I have a column with 595 rows. Then I proceeded to add 20.</p>
  
  <p>(Note this excel sheet with the 595 entries was already in place before I started working on it. The sort feature was working correctly, as was the filter feature).</p>
  
  <p>So now, I can still USE the sort and filter methods, but it does not take into account these 20 new rows. Any ideas?</p>
  
  <p>Also, I cannot remove the borders on these 20 new rows. They are pretty thick and say I just did 'no borders', it doesn't modify anything.</p>
  
  <p>It seems like there's a 'cutoff' at 595 or something. Very weird.</p>
