Steps to do this:
1. Select the cell and change its fill to 'No color'
2. Insert an oval shape and change its fill to 'No color'. You can use a standard oval, a rectangle with rounded corners, or the oval shape from the flowchart symbols for this.
3. Position and resize the shape over the 'TARGET: Senior Software Developer' text.
4. Change the shape's color to whatever you want and set its outline to 'No Outline'
5. Change the shape's wrapping to 'behind text'.
