Has anyone ever had any luck figuring out how to add a comment to Excel using the Open XML SDK 2.0? I couldn't find any documentation on where to get started on this issue.

Another possibility, (which I used), is to use the HYPERLINK formula for Excel. I needed to create individual hyperlinks in each cell, yet the cells had to display different text, (I had to display tracking numbers in the cells yet have a hyperlink for each tracking number to the carrier's site and had to handle multiple carriers).
Once I instantiated an individual cell, the formula was applied in this manner to each cell (there are undoubtedly numerous way):
// ...
Cell cell1 = new Cell(){ CellReference = "A1", StyleIndex = (UInt32Value)1U, DataType = CellValues.InlineString };
CellValue cellValue1 = new CellValue();
CellFormula cellFormula1 = new CellFormula() { Space = SpaceProcessingModeValues.Preserve };
cellFormula1.Text = @"HYPERLINK(""http://www.theclash.com"", ""Radio Clash"")";
cellValue1.Text = "Radio Clash";
cell1.Append(cellFormula1);
cell1.Append(cellValue1);
// append cell, etc.
In this way, I was able to create individual hyperlinks and text for each cell. By the way, the links will appear with the default font color unless you reference a style with blue font.
Hope this helps.
I think this should do what you're asking. The other function is there just to deal with if you have shared strings, which I assume you do in your column headers. Not sure this is perfect, but I hope it helps.
static void Main(string[] args)
{
DataTable dt = new DataTable();
using (SpreadsheetDocument spreadSheetDocument = SpreadsheetDocument.Open(@"..\..\example.xlsx", false))
{
WorkbookPart workbookPart = spreadSheetDocument.WorkbookPart;
IEnumerable<Sheet> sheets = spreadSheetDocument.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>();
string relationshipId = sheets.First().Id.Value;
WorksheetPart worksheetPart = (WorksheetPart)spreadSheetDocument.WorkbookPart.GetPartById(relationshipId);
Worksheet workSheet = worksheetPart.Worksheet;
SheetData sheetData = workSheet.GetFirstChild<SheetData>();
IEnumerable<Row> rows = sheetData.Descendants<Row>();
foreach (Cell cell in rows.ElementAt(0))
{
dt.Columns.Add(GetCellValue(spreadSheetDocument, cell));
}
foreach (Row row in rows) //this will also include your header row...
{
DataRow tempRow = dt.NewRow();
for (int i = 0; i < row.Descendants<Cell>().Count(); i++)
{
tempRow[i] = GetCellValue(spreadSheetDocument, row.Descendants<Cell>().ElementAt(i-1));
}
dt.Rows.Add(tempRow);
}
}
dt.Rows.RemoveAt(0); //...so i'm taking it out here.
}
public static string GetCellValue(SpreadsheetDocument document, Cell cell)
{
SharedStringTablePart stringTablePart = document.WorkbookPart.SharedStringTablePart;
string value = cell.CellValue.InnerXml;
if (cell.DataType != null && cell.DataType.Value == CellValues.SharedString)
{
return stringTablePart.SharedStringTable.ChildElements[Int32.Parse(value)].InnerText;
}
else
{
return value;
}
}

The below code will take the worksheet that you want to add comments to and then iterate over the commentsToAdd dictionary. The dictionary key is the cell reference (ie. A1) and the value is the comment text to be added.
