Text borders (all in Word)
Word has the ability to have horizontal lines between lines in a document (see the attachment), but when opened in Libreoffice the interior lines disappear.
This appears to be a deficiency in Libreoffice formatting (there are no interior line options in "Paragraph -> Borders -> Line Arrangement").
It does appear that the ODT format (as supported in Word 2013) does not support interior lines as well (I tried exporting to ODT and then reopening with Word to see what happened), so this might need an addition to the standard.
Google Docs appears to support the interior lines (but the google drive viewer doesn't).
Uncheck the option "Merge with next paragraph" in the tab "Borders" in the paragraph properties. To avoid a gap between two paragraphs, use a line spacing without leading, "single" or "proportional 100%".
[There seems to be an error in line spacing, but that is a different topic.]
Your workaround does work.
It seems odd that libreoffice wouldn't try and detect that sort of thing though.
Set to NEW as it's labelled as enhancement.
It's on devs and ODF specialists to decide to implement it or not.
If somebody disagrees please close the bug.
