.net 如何使用 EPPlus 设置 XLSX 单元格宽度

你好，我有这个代码，我创建了一个xlsx文件，我需要预先设置xlsx表格单元格的宽度.

using (ExcelPackage p = new ExcelPackage())
            {
                String filepath = "C://StatsYellowPages.csv";
                DataSet ds = ExportCSVFileToDataset(filepath, "tblCustomers", "\t");
                //Here setting some document properties              
                p.Workbook.Properties.Title = "StatsYellowPages";

                //Create a sheet
                p.Workbook.Worksheets.Add("Sample WorkSheet");
                ExcelWorksheet ws = p.Workbook.Worksheets[1];
                ws.Name = "StatsYellowPages"; //Setting Sheet's name

                //Merging cells and create a center heading for out table
                ws.Cells[1, 1].Value = "StatsYellowPages";
                ws.Cells[1, 1, 1, ds.Tables[0].Columns.Count].Merge = true;
                ws.Cells[1, 1, 1, ds.Tables[0].Columns.Count].Style.Font.Bold = true;
                ws.Cells[1, 1, 1, ds.Tables[0].Columns.Count].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;

                int colIndex = 1;
                int rowIndex = 2;

                foreach (DataColumn dc in ds.Tables[0].Columns) //Creating Headings
                {
                    var cell = ws.Cells[rowIndex, colIndex];

                    //Setting the background color of header cells to Gray
                    var fill = cell.Style.Fill;
                    fill.PatternType = ExcelFillStyle.Solid;
                    fill.BackgroundColor.SetColor(Color.Gray);


                    //Setting Top/left,right/bottom borders.
                    var border = cell.Style.Border;
                    border.Bottom.Style = ExcelBorderStyle.Thin;
                    border.Top.Style = ExcelBorderStyle.Thin;
                    border.Left.Style = ExcelBorderStyle.Thin;
                    border.Right.Style = ExcelBorderStyle.Thin;

                    //Setting Heading Value in cell
                    cell.Value = dc.ColumnName;

                    colIndex++;
                }

                foreach (DataRow dr in ds.Tables[0].Rows) // Adding Data into rows
                {
                    colIndex = 1;
                    rowIndex++;
                    foreach (DataColumn dc in ds.Tables[0].Columns)
                    {
                        var cell = ws.Cells[rowIndex, colIndex];
                        //Setting Value in cell
                        cell.Value = dr[dc.ColumnName].ToString();
                        //Setting borders of cell
                        var border = cell.Style.Border;                      
                        colIndex++;
                    }
                }


                //Generate A File with Random name
                Byte[] bin = p.GetAsByteArray();
                string file = "c:\\StatsYellowPages.xlsx";
                File.WriteAllBytes(file, bin);
