There is an issue when adding rows near an Excel ListObject containing formulae in its listColumns.
Basically when the amount of added rows intersect the table below, its formule are copied upward.
Here is the code to reproduce the issue:
Workbook wb = new Workbook(“Test.xlsx”);
wb.Worksheets[0].Cells.InsertRows(4, 3);
wb.Save(“TestOutput.xlsx”);
