    so I have a row on a table using the tableWidget but I want to remove data from the row without deleting the entire row, and hence reuse the row to add other data. I have tried using removeRow but that deletes the entire row which isn't what I am after. I have also tried setting the row to no value with setItem() but that still does not work so can you help!

    Thanks!

    @BlueBreezy You can iterate through all columns in that row using https://doc.qt.io/qt-5/qtablewidget.html#item and delete/clear content of each item.

    "I have also tried setting the row to no value with setItem() " - can you show how you did this?

      Ok thanks I will try that, and how I set it to no value is by doing this ```

      window.tableWidget.setItem(0,0 ,QTableWidgetItem())

      as you can see QTablewWidgetItem is blank and there is no value in the parenthesis

          It is, but it is the same interface in Python but with Python syntax...

            @jsulm So can the same be found here https://doc.qt.io/qtforpython/PySide2/QtWidgets/QTableWidget.html

            also its just

            QTableWidget::item(int row, int column) const
            

            so how would I go about deleting a row with just that?

              You don't want to delete a row, right? You want to remove the content in all cells in a row if I understood you correctly. Using item(...) you get the item in the given cell and can then reset its content. For example if you have text in an item you can use https://doc.qt.io/qt-5/qtablewidgetitem.html#setText to set empty string in it.

                  @jsulm but I think I tried setting the row no no value before but whenever my code tries to put data into it it skips the row because it thinks that there is data there, here's an example

                  window.tableWidget.setItem(0,0 ,QTableWidgetItem())

                    @BlueBreezy I did not suggest to call setData. I suggested to call

                    window.tableWidget.item(row, col).setText("");
