QTextDocument: add css-styling of table cell borders to HTML import/export
Supported style attributes: <table> style: supports "border-collapse: collapse" and "border-color". border: width of the outer border bordercolor: basic color for all borders <tr> style: not supported <td>/</th> style: supports the "border", "border-[top|left|bottom|right]]" shorthand styles and the "border-width", "border-color" and "border-style" (and the top/left/bottom/right variants) attributes <table border=1 style="border-collapse: collapse"> will render a simple 1px table grid. Notes: The QTextDocument table model is much simpler than the HTML table model. It basically only has <table> and <td> support. So the HTML parser is forced to map markup and styling to the QTextDocument model which is not without loss. In other words: While QTextDocument -> HTML -> QTextDocument should preserve the QTextDocument structure, HTML -> QTextDocument -> HTML does not preserve the HTML DOM at all. So for now the HTML importer and writer only support border styles on the <td> and <th> nodes. In future updates, the HTML parser might be enhanced to map <tr> and <table> CSS styles to the cells.
