When applying a table or table cell border with no thickness specified, the border is exported with a default thickness value of zero. However, by specification, the default value should be 2.

Workaround: Create a border by specifying the thickness value. For example:

table.Borders = new TableBorders(new Border(thickness, BorderStyle.Single, new ThemableColor(Colors.Black)));

The Spacing Before property of the paragraph at the start of the page should not be respected if it is not the first one inside the current section.

Manually overriding the Spacing Before property would resolve the issue.

InvalidOperationException when cloning a document containing fields spanning multiple paragraphs.

Workaround: instead of new paragraphs, use line breaks (Shift+Enter).

Extend the support for em units. Em is calculated relatively to the font-size style property.

When importing a simple table from HTML in Ms Word, it gets applied table cell spacing and margin. This makes it look more in the manner it does in a browser, i.e. the content of cells is vertically centered.
