Changing text alignment in custom report on customer portal

Content

Hello dears,

I am using a custom report on the "Account Overview" page on the customer portal. I would like to have all column data text aligned to "center" except for one column, whose data should keep the original text alignment (left). I have achieved this in the report designer by editing the format of these columns; however, the changes are not reflecting on the customer portal page for this report.

Any idea why this is happening? And how can I reflect my changes on the portal?

Thanks,

Hanna
