Feature Request: Support custom table styles

Currently, the user can only specify a built-in style name when creating a worksheet table via the style option when calling add_table() and xlsxwriter always writes an empty tag to the tableStyles element. The Workbook class will need a new method for add_table_style() and the Styles class _write_table_styles() method will need to support writing the appropriate tags. I’ll submit a PR for this shortly.

Could you explain this a bit more.

Sure. When you call worksheet.add_table(), you can specify a style name in the options (http://xlsxwriter.readthedocs.io/working_with_tables.html), e.g. sheet.add_table('B3:F7', {'style': 'Table Style Light 11'}). This style name has to be a built-in style, you can’t create your own so you’re limited to the color/format choices that Excel gives you (21 light, 28 medium, and 11 dark themes).

It would be nice to be able to specify the format for a new table style, which we create through xlsxwriter, and then specify by name when calling worksheet.add_table().

Adding this functionality involves minimal changes to Packager._write_styles_file(), a few small changes to Styles._write_table_styles() and the addition of Workbook.add_table_style() as a public method (plus documentation and tests).

Closing as I am unlikely to tackle this.
