Differences in borders between Excel and LibreOffice Calc. The sources for this Document is: - sc/qa/unit/data/ods/test_borders_export.ods (new Test-Document) - sc/qa/unit/subsequent_export-test.cxx (ScExportTest::testBordersExchangeXLSX) - sc/source/filter/excel/xestyle.cxx (void lclGetBorderLine) - sc/source/filter/oox/stylesbuffer.cxx (Border::convertBorderLine) Bug-Ticket: tdf#79787 In LibreOffice the lines are defined by two information: the style and the width of the line. There are seven different line styles available. And the following line width can be selected: 0.05 pt, 0.25 pt, 0.50 pt, 0.75 pt, 1.0 pt, 1.25 pt, 1.50 pt, … until 9pt. In Excel you can only define the style of the line. There are 13 different styles available. The width cannot be entered explicitly, instead you have different styles for a solid line with different width (s. Screenshots below). The question is now: how to map the borderlines of LibreOffice to Excel and vice versa. In the overview below you can see the mapping as it is and some suggestions how to improve it. As the borders are defined different, it will not be possible to define a 1:1 mapping." The current mapping is mainly defined of the width, but i think better is the line-style, i think user see that first Base for the evaluation is LibreOffice master (commit [bbfeab3b13b48c99cfa2f94c8c34bc3efef7faa9] ) and Excel 2013 EXCEL || LIBREOFFICE Excel-Line Name Value || LO-Line Name Value None EXC_LINE_NONE 0 || none table::BorderLineStyle::NONE 32767 (-1) 1 EXC_LINE_HAIR 7 || 1 table::BorderLineStyle::SOLID 0 2 EXC_LINE_DOTTED 4 || 2 table::BorderLineStyle::DOTTED 1 3 EXC_LINE_THIN_DASHDOTDOT 11 || 3 table::BorderLineStyle::DASHED 2 4 EXC_LINE_THIN_DASHDOT 9 || 4 table::BorderLineStyle::FINE_DASHED 14 5 EXC_LINE_DASHED 3 || 5 table::BorderLineStyle::DASH_DOT 16 6 EXC_LINE_THIN 1 || 6 table::BorderLineStyle::DASH_DOT_DOT 17 7 EXC_LINE_MEDIUM_DASHDOTDOT 12 || 7 table::BorderLineStyle::DOUBLE_THIN 15 8 EXC_LINE_MEDIUM_SLANT_DASHDOT 13 || 9 EXC_LINE_MEDIUM_DASHDOT 10 || 10 EXC_LINE_MEDIUM_DASHED 8 || 11 EXC_LINE_MEDIUM 2 || 12 EXC_LINE_THICK 5 || 13 EXC_LINE_DOUBLE 6 || In the following cases a 1:1 mapping is not possible.
