I Writer, you cannot have empty space below a table; at least, there has to be
an empty paragraph.

MRU->ALCI: as a workaround, place the cursor in the mentioned paragraph and in
Format.Paragraph.Text flow remove the "page break" option.

MRU->FL: but I think, we could make the behaviour a bit more intuitive here, so
that a paragraph containing a page break following a table will lose its page
break when pressing "Backspace" in this case.

Thanks for the workaround.

By the way, is the fact that OOo always insert an empty paragraph after a table 
considered a feature ?

It is not convinient when you use a table in a page header for example (which 
is very common practice for a logo, date of creation, project name, ...), as 
you have to set the font size of this empty paragraph to a very little number 
to avoid loosing to much space...

Set target.

Would having an empty space (instead of an empty paragraph) below a table be a 
possible enhancement ?

Use case is :

- I want to put a table in a header to handle information such as date of 
creation, author, logo and so on in a structured manner
- I don't want an empty line under the table, since I already have a blank 
space between the header and the main text
- I don't want to have to set the font size to 2 to avoid loosing so much 
space and giving an unclean feeling

@alci: If you do not import something but write directly in OOo, there is a
trick for getting a table without following paragraph into the header: Remove
all tabstops from header; Write a line with so much tabs a you want columns;
Mark the line;  Table > Convert > Text to table.
