Export the Writer document to html and have a look at the file with your browser.
Open the attached Writer-file.
There is a table, which has been formatted by Table > AutoFormat Styles...
Export this table to html or download the exported html-file.
The borders of the table doesn't appear in the exported html-file.
Here is one line of the code:
<td width="25%" bgcolor="#00599d" style="background: #00599d" style="border-top: none; border-bottom: 1px solid #00599d; border-left: none; border-right: none; padding: 0cm" sdnum="1031;0;@"><p align="left" style="font-style: normal; text-decoration: none">
1) background is defined twice, as bgcolor and as style.
2) the definition of styles appears two times so the first style-definition destroys the second style-definition. Second style-definition won't be recognized by the browser.
1) remove style="background: #00599d"
2) remove the old bgcolor-definition and set the background-style as part of the other styles: style="border-top: none; border-bottom: 1px solid #00599d; border-left: none; border-right: none; padding: 0cm; background: #00599d;"
Note: Good CSS-definition ends every time with ";".
This bug won't appear with LO 5.1.5, first appears here with LO 184.108.40.206 and also with LO 220.127.116.11 on OpenSUSE 15 64bit rpm Linux.

Problem and solution with "save as" (HTML4) without any aspects of HTML5 are little bit different from the OP. The expression "bgcolor" doesn't cause any problem here, and the (manual) solution is remove 'style="background: #......' with a texteditor using "regular expression".
This seems to have begun at the below commit.
