title: How to update a XSLFTable (table in .pptx presentation) using Apache POI?
body: <p>I'm working with Apache POI and I'm trying to automate some tasks with Powerpoint reports. More precisely, I would like to update the data inside a .pptx presentation from code, including tables.</p>
  
  <p>I've managed to get the XSLFTable objects (thanks to this page : <a href="https://stackoverflow.com/questions/19975379/how-to-modify-the-cell-value-of-a-table-in-an-pptx-file-with-apache-poi-3-9">How to modify the cell value of a table in an pptx file with apache-poi 3.9?</a>), but now I'm trying to update the table structure.</p>
  
  <p>Unfortunately, I don't know how to create or remove rows (or columns) in that table. The method <code>getRows</code> returns a list, but it seems unmodifiable. There is a <code>addRow</code> method, but I didn't find anything to delete/remove rows. </p>
  
  <p>Do you know how I can achieve that?</p>
  
  <p>Thanks a lot, and best regards!</p>
