I want to create an 'universal' XML spreadsheet compatible document... Something compatible both with Microsoft Excel and especially with the open source alternatives (OpenOffice Calc, Gnumeric, ..).
There's an issue I encounter when I try to border some cells. This is how you do it in Excel:
<Border ss:Position="Bottom" ss:LineStyle="Continuous" ss:Weight="6"/>
<Border ss:Position="Left" ss:LineStyle="Continuous" ss:Weight="6"/>
</Borders>
And here's a Gnumeric example:
<gnm:StyleBorder>
<gnm:Bottom Style="1" Color="0:0:0"/>
<gnm:Left Style="1" Color="0:0:0"/>
</gnm:StyleBorder>
Is there a standard approach?
