If you want to edit a single cell value directly similar to spreadsheet editing, you can easily do by enabling "tableCellEdit".
On click on table rows, it shows the value inside the input text box. You can edit the value inside the input type text.
You need to press enter to save the value. You can click on any table cell to edit the value directly.
Limitations:
$pdocrud = new PDOCrud();
$pdocrud->setSettings("tableCellEdit", true);
echo $pdocrud->dbTable("orders")->render();
