This is a known issue. Here's a workaround for it:
1. Change Font Color to be Automatic:
2. Excel 2007 or higher > Home Tab > ''Styles'' Group > Cell Styles
3. Right Mouse click on ''Normal'' style > Modify
4. Click ''Format'' > ''Font'' tab
5. Choose ''Color'' > ''Automatic''
6. Save the XLS file.
Remember that the DataTable is NOT an Excel spreadsheet and does not accept all of the formatting and formulas that Excel does. Here's some links that will help clean formatting:
