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.
