Add padding to bordered paragraph
"Cell padding" as such does not exist in Word, but you can try these:
(I have Word 2007 2010 for Windows right now, but the commands should be similar)
- Open Borders and Shading dialog (Ribbon -> Home Tab, Paragraph sub tab, click on the arrow near the "Borders" icon)
- Click on "Borders and Shading"
- Click on "Options..."
- Adjust the values in "From text"
For the left and right "padding" the "Left Indent", "Right Indent" and "Hanging Indent" handles in the ruler may help (View Tab - > Show/Hide -> Ruler if the ruler is not visible)

Edit: Added images (realized after 3 years, screenshots from Word 2010, instructions pretty much the same)
