我正在使用 EPPlus 将一些信息导出到 excel 中，并且在使用公式的总计行中遇到了一个绊脚石。打开文件时只计算第一个公式，其他公式只在我双击进入和离开公式单元格时计算。下面是构建表的代码和结果。希望有人可以为我提供一些有关如何解决此问题的见解。
private void BuildSalesTable(string label, ISalesTable table)
{
var sheet = ExcelPackage.Workbook.Worksheets.Add(string.Format("Sales{0}", label));
//table header
//BuildHeader(startRow, 2, startRow, 9, string.Format("Sales Tons - {0}", label));
//table lables
sheet.Cells[1, 2].Value = "Joist Qtd";
sheet.Cells[1, 3].Value = "PP/Ton";
sheet.Cells[1, 4].Value = "Deck Qtd";
sheet.Cells[1, 5].Value = "PP/Ton";
sheet.Cells[1, 6].Value = "Joist Sold";
sheet.Cells[1, 7].Value = "PP/Ton";
sheet.Cells[1, 8].Value = "Deck Sold";
sheet.Cells[1, 9].Value = "PP/Ton";
for (int i = 0; i < table.Rows.Count; i++)
{
var row = 2 + i;
//every other row coloring
if (i == 0 || i%2 == 0)
{
sheet.Cells[row, 1, row, 9].Style.Fill.PatternType = ExcelFillStyle.Solid;
sheet.Cells[row, 1, row, 9].Style.Fill.BackgroundColor.SetColor(Color.Khaki);
}
//data
sheet.Cells[row, 1].Value = table.Rows[i].Location;
sheet.Cells[row, 2].Value = table.Rows[i].JoistQuoted;
sheet.Cells[row, 3].Value = table.Rows[i].JoistQuotedPP;
sheet.Cells[row, 4].Value = table.Rows[i].DeckQuoted;
sheet.Cells[row, 5].Value = table.Rows[i].DeckQuotedPP;
sheet.Cells[row, 6].Value = table.Rows[i].JoistSold;
sheet.Cells[row, 7].Value = table.Rows[i].JoistSoldPP;
sheet.Cells[row, 8].Value = table.Rows[i].DeckSold;
sheet.Cells[row, 2].Value = table.Rows[i].JoistQuoted;
sheet.Cells[row, 9].Value = table.Rows[i].DeckSoldPP;
}
//totals row
sheet.Cells[table.Rows.Count + 2, 1].Value = "Total";
sheet.Cells[table.Rows.Count + 2, 1].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
sheet.Cells[table.Rows.Count + 2, 1].Style.Font.Color.SetColor(Color.Gray);
sheet.Cells[table.Rows.Count + 2, 2].Formula = string.Format("=SUM(B2:B{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 3].Value = string.Format("=SUMPRODUCT(B2:B{0},C2:C{0})/SUM(B2:B{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 4].Value = string.Format("=SUM(D2:D{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 5].Value = string.Format("=SUMPRODUCT(D2:D{0},E2:E{0})/SUM(D2:D{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 6].Value = string.Format("=SUM(F2:F{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 7].Value = string.Format("=SUMPRODUCT(F2:F{0},G2:G{0})/SUM(F2:F{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 8].Value = string.Format("=SUM(H2:H{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 9].Value = string.Format("=SUMPRODUCT(H2:H{0},I2:I{0})/SUM(H2:H{0})", table.Rows.Count + 1);
sheet.Cells[table.Rows.Count + 2, 2, table.Rows.Count + 2, 9].Style.Font.Color.SetColor(Color.DarkBlue);
//format data
sheet.Cells[2, 1, 2 + table.Rows.Count, 10].Style.Numberformat.Format = "#,##0";
sheet.Workbook.CalcMode = ExcelCalcMode.Automatic;
}
Excel 看起来像这样：
