Rendering a THEAD around header row

Hi there,

I am trying to get our older version of ActiveReports (version 4.2.0.1205, I do hope this is the right forum) to render a

<thead>

around our header row on some of our reports.

I don’t know much about this code as I didn’t write it nor much about ActiveReports, but my suspicion is that I should be doing something here:

if (IsSection)
            {
                RSTableRow trs = new RSTableRow();
                trs.CssClass = "";
                RSTableCell tcs = new RSTableCell();
                tcs.CssClass = "sectionHeader";
                tcs.ColumnSpan = tbl.ValidColumns.Count;
                tcs.Text = tbl.SectionText;
                tcs.Attributes.Add("align", "left");
                tb.Rows.Add(trs);
                trs.Cells.Add(tcs);
            }

Any ideas would be great and thanks for your time!
