Cell-comment support on a
TXLSXWorksheet. Each
entry attaches an author plus a free-text body to a cell. SaveAs emits
xl/commentsN.xml with a deduplicated author list and a
companion
xl/drawings/vmlDrawingN.vml ，Excel 才能渲染批注气泡；Open 会把批注 XML 读回集合。声明于
lxHandleX

begin
ws := Workbook.Sheets.Add('Reviews');
ws.Cells.Item[1, 1].Value := 'Q1 revenue';
ws.AddComment(1, 1, 'Numbers still pending review', 'Kevin');
// Equivalent through the collection:
ws.Comments.Add(2, 1, 'Auto-generated draft');
if ws.Comments.IndexOfCell(1, 1) >= 0 then
ws.Comments.DeleteAt(1, 1);
end;
