How to set center vertical alignment of MergeCell by OpenXml with C#, below code snippet is my MergeCell implementation in C#
mergeCells.Append(new MergeCell() { Reference = new StringValue("A2:A4") });
worksheetPart.Worksheet.InsertAfter(mergeCells, worksheetPart.Worksheet.Elements<SheetData>().First());
But the text value in merged cell was moved to right corner, how can I move to center of merged cell?
Thank you in advance
