Test odt file with tables

I needed to make some tables with solid background over some arrays of cells. What I did was:

-I selected the whole table and made borders invisible (or created one and deselected "border" at the dialogue box).
-I selected the array of cells, and selected a background color. The array was effectively painted with that color. At that point the borders were still visible in the odt, as they should for visual aid during text editing.
-I exported to pdf. The "invisible" borders were still there, as fine white lines. They were only invisible when the background was itself white.

To illustrate, I attach an odt with two tables and its resulting pdf.

Note for the style of the border line I could not select "none", nor could I select a width below 0.05 pt. I don't know if this is by design.

Using LO (Build ID: 40m0(Build:2), Locale: en_US.UTF-8) on Ubuntu 12.04 64bit

Borders show through as fine white lines

Reproducible with LO under Ubuntu 15.04.
It is not a problem with table borders because if you change the border color, you still get the same line color in the pdf.
Same problem if I print using a virtual pdf printer or if I print in a file.

Set status to NEW.

Best regards. JBF

Sorry, I take that back!

The borders are invisible when viewed with Okular, but they are still there with Document Viewer or in Firefox.

I reopen this bug.
