Rowspan Don't Work

Hey Guys,

I’m leaving Outlook in my company, and I’m starting using eM Client, there may be some setting I do not know.
Well, all the signatures of all employees of my company have a “rowspan” light blue, between the company logo and employee information. Outlook normally appear this rowspan, but in eM Client does not appear.

Images below.
