title: Writing to a particular cell location using Apache POI Excel
body: <p>If I've got an list of parameters 'x,y,z' that aren't sorted, is there a straightforward way to write them to particular cells in an excel document created with POI, as though the first two parameters are X and Y coordinates?</p>
  
  <p>For example, I have rows like: </p>
  
  <pre><code>10,4,100
  </code></pre>
  
  <p>Is it possible to write the value '100' in the cell at the 10th row, 4th column?</p>
  
  <p>Looking at the documentation, it looks straightforward to iterate values into the next row, but I can't see any way of creating a fixed number of rows and columns and writing particular values to only certain cells.</p>
  
  <p>Any advice or suggestions would be appreciated, thanks!</p>
