Reproducibility

Always:

• Add new Table Style
• Set “Whole Table” to “No Borders”
• Copy a sheet with ClosedXML an save it
• Open with Excel and get the above error

Code to reproduce problem:

static void Main(string[] args) {
            File.Copy("test.xlsx", "copy.xlsx", true);
            using XLWorkbook wb = new("copy.xlsx");

            bool res = wb.TryGetWorksheet("Original", out IXLWorksheet sheet);

            sheet = sheet.CopyTo(wb, "copy");

            wb.Save();
            
        }

Not any concrete plans. Priority ATM is to deal with PRs.

Just encountered a similar (if not the same) bug on the latest version (0.101.0) Just having any custom table style “corrupts” the worksheet when saving again:

using ClosedXML.Excel;

using XLWorkbook workbook = new(@"Test.xlsx");
workbook.SaveAs(@"Outputxlsx");

The excel file Test.xlsx is completly empty except a single custom table style. Maybe this helps whenever somebody finds some time to look into this issue.
