How to update a XSLFTable (table in .pptx presentation) using Apache POI?

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.

I've managed to get the XSLFTable objects (thanks to this page : How to modify the cell value of a table in an pptx file with apache-poi 3.9?), but now I'm trying to update the table structure.

Unfortunately, I don't know how to create or remove rows (or columns) in that table. The method getRows returns a list, but it seems unmodifiable. There is a addRow method, but I didn't find anything to delete/remove rows.

Do you know how I can achieve that?

Thanks a lot, and best regards!

Get XSLFTable 

XSLFTable t = null;
for (XSLFShape shape : slide) {
    if (shape instanceof XSLFTable) {
        t = (XSLFTable) shape;
        r = t.getRows();
   }
}

Add Row and Cell

XSLFTableRow titleRow = tbl.addRow();
titleRow.setHeight(50);
XSLFTableCell titleCell1 = titleRow.addCell();
XSLFTextParagraph p1 = titleCell1.addNewTextParagraph();
p1.setTextAlign(TextAlign.CENTER);
XSLFTextRun r1 = p1.addNewTextRun();
r1.setText("Column title");
r1.setBold(true);
r1.setFontColor(new Color(0, 104, 145));
titleCell1.setFillColor(new Color(190, 230, 245));
r1.setFontSize(25.0);
titleCell1.setVerticalAlignment(VerticalAlignment.MIDDLE);

Remove Row

t.getCTTable().getTrList().remove(t.getNumberOfRows()-1); //Remove the last row from table.
