Example file from Word 2016

Attached example file contains a table with different number of columns in rows.
In Word the second rows second and third cells have their top border turned off, but in Writer this is visible.

1. Open attached file
2. Notice the cell starting with 2 and the empty one right of it has top border, unlike in Word.

Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 44355a90b3450111ad87ad4b6607a564e41d7b54
CPU threads: 14; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win
Locale: de-DE (hu_HU); UI: en-US
Calc: threaded

and all the way back to 3.6. In 3.5 there was no border imported at all.

If the same example is saved to docx, it had the same import issue fixed in 5.3 times with:

Minimized RTF sample

I've stripped down testcase to minimal for problem to became clear.

As far I see, there is problem with non-rectangular tables:
* first row contains only one cell and border below
* second row contains 2 cells
* in Writer first row is extended to fit entire table width unlike in Word.

I see that for DOCX Writer does creates extra cells in first row to make rectangular table. But it is not done for RTF.
