    @Piyush Simply right click on table widget then "Edit items...". Then you can add/remove columns/rows and you can move them up/down or right/left.

    "Also, while setting any element I am using the following setting any label or any value:" - is this a question?

    @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.

                      @Piyush
                      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.
