Autofit in EPPlus

Question

I cannot find a way to auto-adjust row height using the EPPlus Excel library. When I used Excel Interop, I could do it sheet.Rows.AutoFit(). I am viewing the interface using ILSpy, but so far I have not found anything useful. Is there a way around the problem, or am I missing something?

UPDATE : line 4 gives me problems:

I tried doing sheet.Row (4) .CustomHeight = false, but that didn't work ... I also tried setting the property before and after loading the contents of the cell, and it's still the same. It adjusts the line height to a different value, but this is not very good. Perhaps EPPlus has problems measuring line height? I know that I had a lot of problems with this when I messed up some old GDI + code in which I needed to measure strings ...

        //Setting the height manually will automatically set CustomHeight to true
        //preventing excel from automatically setting the height

        ws.Row(2).Style.Font.Size = 20;

        //row 1 height will be around 26 when opened in Excel (but cannot know that now), 
        //row 2 height will be 30 as set above, 
        //row 3 height will be the DefaultHeight (usually 15) of the worksheet since it can fit the default font

      // Increase the height of the header row by .5
      // (The height is already at 2 times the default value)
      wsDT.Row(1).Height *= 1.5;

      // Column index to Notes, Anniversary Month and Day
      //   add "1" since column index is relative to 0
      int colIdx = dt.Columns.IndexOf("Notes") + 1;

      // Set the column width 
      // This is a long text field - so width and word wrap are set
      wsDT.Column(colIdx).Width = 50;
      wsDT.Column(colIdx).Style.WrapText = true;

      // Set width of anniversary month column
      // Purpose here is to wrap header text
