Hello,
I found a bug related to the use of the macro “Elements SpreadSheet” in Confluence
When I use border on merged cells, and then I export my document on excel file: some cells are not correctly displayed.
Indeed, on the local excel document borders of merged cells are not complete: some cells are ½ or 1/3 bordered.
On the web page it is correctly displayed :

On the excel export, some borders are missing :

Is there a solution for this issue ?
