title: Excel Data Table is Very Slow to Refresh
body: <p>I have an Excel data table linked to a query to an Oracle database.  This data table has both: 
   (1) additional calculated columns (some involving array formulas &amp; MATCHes) added to the data table (based on the queried values), and 
   (2) many dependent formulas spread throughout other tabs</p>
  
  <p>While the query itself is fast to refresh if added to a brand new Excel file exactly as is, the dependent formulas seem to slow down the refresh EVEN WITH CALCULATIONS SET TO MANUAL.</p>
  
  <p>I've tried several things:
  1) Set calculations to manual
  2) Disabled screen updating
  3) Disabled events
  4) Removed calculated columns from data table (just normal formulas)</p>
  
  <p>Nothing seems to help... any ideas?  Thanks.</p>
