* exists in the document. Since I'm creating it from scratch, it obviously
* won't exist. When opened in MS Word, the table style becomes "Normal".
* I manually set alternating row colors. This could be done using Themes,
* but that's left as an exercise for the reader. The cells in the last
* column of the table have 10pt. "Courier" font.
* I make no claims that this is the "right" way to do it, but it worked
* for me. Given the scarcity of XWPF examples, I thought this may prove
