Can’t using SSRS be limiting at times?  There you are trying to draw a simple rectangle in a table and the cell just keeps setting the rectangle to be the size of the cell – but you want it another size!  As originally posted.

The trick here is to remember there is nothing stopping you adding another rectangle inside this first rectangle

  1. Add a rectangle to the cell in your table (yellow background in the screenshot below)
  2. Add a rectangle inside this rectangle, and set its BorderStyle to Solid and BorderWidth to 2pt (red background in the screenshot below)
  3. Finally Insert a textbox showing you expression to the inner rectangle (blue background in the image below.

This will give a layout as shown

Design View

That when the report is run will appear as follows

Published Report View

You can then resize this item to be the size you require for your report.
