Created attachment 180261 [details] Border options available in Excel Excel offers 3 options for border thickness when it comes to solid borders (see first attachment showing these options). I'll call them "Thin", "Medium" and "Thick", since MS does not provide names for them in the user interface. The way LO Calc import these borders is causing a bit of inconsistency, because our import is making the borders look much thicker than they should. For example, if you apply these borders in Excel, save the XLSX document and open it in LO Calc they will appear with excessive border weight. Below I'll attach more files showing the problem, as well as a sample XLSX file. I believe the way we convert border thickness needs to be improved. Or maybe the way we draw these borders in the screen. This is because in Excel, if you zoom in/out the border thickness does not change, whereas in LO Calc zooming affects the thickness of the border drawn in the screen.
