Improve cell border quality when exporting to PDF
Please ensure that formatting applied to cells, especially borders, look as intended when a spreadsheet is exported to PDF.
I've noticed that cells that are bordered using the thin, solid line style show up much thicker when exporting to PDF using the driver built-in to Excel. To illustrate, I created a simple experiment using two columns that are bordering using thin and dotted line styles in colors ranging from black 100% to white 5%. I grabbed a screen shot from Excel (what I want) as well as a screen shot from the exported PDF (what I get).
