Got It:
DataTable dt = ds.Tables[0];
var clsXLWorkbook = new XLWorkbook();
var ws = clsXLWorkbook.Worksheets.Add(dt);
ws.Tables.First().ShowAutoFilter = false;
DataTable dt = ds.Tables[0];
var clsXLWorkbook = new XLWorkbook();
var ws = clsXLWorkbook.Worksheets.Add(dt);
ws.Tables.First().ShowAutoFilter = false;
