        <pre>I think, that is mainly a problem of Excel not of LibreOffice. The dotted line
is the way Excel renders a hairline. Excel has only a fixed set of line styles.
These line styles include already the thickness, there exist no separate
setting for thickness.
LibreOffice uses a mapping between LO styles and Excel styles, see
<a href="https://opengrok.libreoffice.org/xref/core/sc/source/filter/excel/xestyle.cxx?r=b7ed6de5#1608">https://opengrok.libreoffice.org/xref/core/sc/source/filter/excel/xestyle.cxx?r=b7ed6de5#1608</a>
In this case the line is 0.06pt and therefore falls into case hairline.
Details about mapping are in
<a href="https://opengrok.libreoffice.org/xref/core/sc/qa/unit/data/README.cellborders?r=6777720c">https://opengrok.libreoffice.org/xref/core/sc/qa/unit/data/README.cellborders?r=6777720c</a>

Nevertheless one might consider to change the mapping to base it mainly on
style and not on thickness.</pre>
