Thanks for the PR. There is definitely something here, but I'm not sure this is the answer. Have you succeeded to add a border to the end of a row (in blank cells) with your additional code?

Because appendRepeatedCell has really a bad name: it should be insertBlankCells or something like that, because it only add cells without any content or style. It exists only to skip blank cells between the cells with real content. Hence, adding such blank cells after the last cell with content will have no effect (I mean: in Calc display, because it will obviously add some tags to the XML file).

If you want to have blank cells with a style, you should write something like:

    walker.next();
    walker.setVoidValue(); // this is not a blank cell
    walker.setStyle(myStyle);

Note: I found a mistake in CellType (type and attribute are swaped), thanks to your PR.
