Published range, no line between cells

Published range, no line between cells

Hello and thanks for this very useful app!

Question is, I use a published range (iframe) as our organization's calendar --  http://www.ruhaniat.org/index.php/2012-06-04-19-59-45

When I look at the sheet in sheet.zoho.com there are fine border-lines between cells. But not when viewing it in as published. There's nothing separating the cells.

Is there a way to make the cell borders visible in the published view ??

Thanks              -- Howard Ballinger
