C# closedxml设置行高删除背景色

我试过各种组合。如果我设置了高度，则第一行背景色始终为白色。ClosedXML 0.95.3

        using (var workbook = new XLWorkbook())
        {
            var toc = workbook.AddWorksheet("table of contents");
            toc.Style.Fill.SetBackgroundColor(XLColor.FromHtml("#16365C"));
            toc.Row(1).Height = 35;
            toc.Column(1).Width = 19;
            toc.Column(2).Width = 200;
            toc.Row(1).Style.Fill.SetBackgroundColor(XLColor.FromHtml("#16365C"));
            workbook.SaveAs(ms);
        }
