c# EPPlus: how to fix - ShowFilter doesn't work - epplus

Question

The issue with Table.ShowFilter, using EPPLUS library.
Created new ExcelTable in the sheet, but can't apply Table.ShowFilter = false.
The filters are still in the table.
TableStyle and StyleName work fine.
ExcelTable et = (ExcelTable)Table;
int firstRow = newRow;
int lastRow;
if (DataStructure.Data != null)
lastRow = newRow + DataStructure.Data.Count();
else
lastRow = newRow + 1;
int firstColumn = OriginalAddress.StartColumn;
int lastColumn = OriginalAddress.EndColumn;
ExcelRange rg = ws.Cells[firstRow, firstColumn, lastRow, lastColumn];
Guid guid = Guid.NewGuid();
string str_guid = guid.ToString();
string tableName = et.Name + "_" + str_guid;
ExcelTable tab = wsTarget.Tables.Add(rg, tableName);
// tab.ShowHeader = et.ShowHeader;
// tab.TableStyle = et.TableStyle;
// tab.StyleName = et.StyleName;
tab.ShowFilter = false;
Right table is desired result.
Please, help to fix!

Answer 1

Is this you want to mean?
tab.ShowHeader = false;
This very little example works here :
using (ExcelPackage xls = new ExcelPackage())
{
ExcelWorksheet ws2 = xls.Workbook.Worksheets.Add("f1");
OfficeOpenXml.Table.ExcelTable tab = ws2.Tables.Add(new ExcelAddressBase("a1:e5"), "table");
//tab.TableStyle = et.TableStyle;
//tab.StyleName = et.StyleName;
tab.ShowFilter = false;
FileInfo f = new FileInfo(#"d:\temp\test.xlsx");
xls.SaveAs(f);
}

Answer 2

Probably, the bug.
Adding ws2.DeleteColumn(1, 1) to the code, add filters to the table, even with tab.ShowFilter = false.
Workaround: put tab.ShowFilter = false right before file saving.
using (ExcelPackage xls = new ExcelPackage())
{
ExcelWorksheet ws2 = xls.Workbook.Worksheets.Add("f1");
OfficeOpenXml.Table.ExcelTable tab = ws2.Tables.Add(new ExcelAddressBase("d3:g8"), "table");
//tab.TableStyle = et.TableStyle;
//tab.StyleName = et.StyleName;
ws2.DeleteColumn(1, 1);
tab.ShowFilter = false;
FileInfo f = new FileInfo(#"test.xlsx");
xls.SaveAs(f);
}
