RDLC tablix colspan equivalent

rdlc, reporting-services, ssrs-tablix

Solution

The answer was to select all the cells, right click and choose merge cells.

Problem

Is their some sort of colspan equivalent for the RDLC markup? I of course tried colspan and the report doesn't render in design view then, deserialaztion error. The project and zipfile are much longer than the single column to display.
