I'd like to know if it's possible to change the border type for tables in the Content view or if the "border = n" is the only parameter available to define different border types. In particular, using scripting, is it possible to define plain or dotted or dashed border using standard html definitions? And how to apply different border type to different parts of a single table (to separate totals from details, for example)
If you need to use full HTTP/CSS capabilities you can switch to use the native browser Tools->Other->"Use native browser". Please note that in this case the design mode is not available.
