    @jsulm I forgot to mention this earlier, but in this tablewidget i have kept the vertical and horizontal headers as hidden. All the row/column headers in this are actually written on cell itself. Likewise, I have different header on Gray cells.

    In this case if I want to add any value in between then how should I proceed?

    The sample code lines were just for example to show that my header are inserted in cells

    @Piyush Maybe I don't understand something, but what's the difference? You still can add/remove rows/columns.

      @jsulm I am actually using one tablewidget for multiple tables. Therefore, I have not used the column/row header and added the same in form of items in the widget. I have created the tablewidget in the following way:

      Screenshot for edit table, column tab:

      0_1518413900698_77b5c92f-2769-46cc-b502-cb43528e582e-image.png

      Row tab:
      0_1518413985583_b2268b6f-9e8d-49e5-be67-4a0874d1a541-image.png

      Items tab:
      0_1518414040182_d4b023a3-c8b8-4123-b456-c01cd24ea0aa-image.png

      In items tab there will be headings in the grey area. This enables me to add multiple table in single tablewidget.

      So, the issue arrives when I need to add something in the middle. As you said that, we can add/remove rows/columns. But, currently I cannot do that.

      Does that mean I have to redesign the whole tablewidget? Use column and rows tab and then do the editing like I did. Is that correct. Is there any way I can do the same without redesigning? (just add columns/rows and copy paste all the items in one go)

        @Piyush If you need to add a row in the middle then first add it via + button, then select it and move it to the place where you want to have it using the up button (arrow shoing up). Is this working?

          @jsulm That is not working. It adds the row on the top which cannot be moved/shifted down using the arrow keys

              @mrjj please have a look at my previous comment. I have explained the case in that.

                Hi
                If there is no rows and cols , there can be no items.
                So im really not sure what you are asking. :)

                  @mrjj Hi

                  If we do the following in QT Designer on a blank tablewidget, then we have blank items without any rows/columns appearing under rows/columns tab.

                    Ahh , in that way :)
                    yeah that is the same it seems,
                    except u cant move rows up and down as they are not there :)
                    Hmm, yes i see your point. its then not possible to add row in the middle since rows before and after
                    do not really exists for it.

                      @Piyush What if you don't set fix number of rows and columns? Just add everything in this item editor.

                        @jsulm If we do not set fix number of rows/columns, then we first need to add rows/columns from rows/columns tab. Then it becomes dynamic in the way that we can move rows up/down/delete. Thanks.

                        @mrjj Yeah. I will have to make it again in a dynamic way. Thanks for the discussion.
