title: Instantiate Handsontable with no data
body: <p>Seems like a simple task yet I haven't found a simple solution yet. My data sometimes comes as an empty array so that the user can start working off of an empty table (except for the headers). The table has a <code>minSpareRows:1</code> so I was hoping the table would appear with that spare row and nothing else but instead it goes entirely blank.</p>
  
  <p>Any ideas on how to instantiate a table with just the spare row and the column headers?</p>
  
  <p>Things I've tried include manually inserting a row if the data array is empty however this leads to there being an empty row plus a spare row. </p>
