Shrinking of cell when report gets exported in excel

Hi all,

I have report with 8 tabs.All tab contains two cells; one for report tab name and other for date.

When user exports report in excel, In some tabs these two cell gets shrink.means those cells gets merge with neighbouring cells.so user have to manually remove that merge in excel.

is there in setting in Webi to get the same report in excel(without shrinking).
