Why does merging of cells in a table not work on all cells?

[Giovanni]

I want to merge some cells in a table, so I select several cells and click on merge cells. For example I select 3 cells in the first column, and it works properly. Then I select the next 3 cells, and nothing happens after "pushing the button". The 3 cells before I can unmerge and merge several times, but the next 3 do not work. This happens several times within the table, and I didn't figure out yet, what is the cause to make it work or not. Please help me soon, because a customer is waiting for a finalized documentation in his Confluence-Wiki.

My customer uses a self-managed Confluence Version 7.3.1.

Thanks in advance for your professional support and hints.

Hi Giovanni,

welcome to the Community!

I came across the same effect when editing a quite large table. What helped in some cases was to click into a cell and extend marked cell area with keyboard by holding "Ctrl" + "Shift" pressed.

By no means I was able to get to the bottom of the case. I don't think the keyboard-based approach makes much difference. It might rather be a coincidence.

Cheers,
Daniel

Yes I agree, in the end my work-around was to copy/paste working cells or add new cells, till it worked to connect them. I also think that it's maybe a bug. Thank you for your reply!

Why is this the accepted answer? Why is this answer accepted at all and the topic marked as solved? There is no solution in it as stated by the author himself.

Workaround which works for me: Use another browser (In my case Safari works instead of Firefox)
