[英]Merge cells using EPPlus?
我正在使用 EPPlus 庫讀取/寫入 Excel 個文件: http://epplus.codeplex.com/
我試圖在編寫文檔時簡單地合並一些單元格:
using (ExcelPackage pck = new ExcelPackage())
{
//Create the worksheet
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo");
//Format the header for column 1-3
using (ExcelRange rng = ws.Cells["A1:C1"])
{
bool merge = rng.Merge;
}
}
有一個名為 Merge 的屬性,它只返回 true 或 false。 我想也許這會合並單元格,但事實並非如此。
有人知道怎么做嗎?
你必須像這樣使用它:
ws.Cells["A1:C1"].Merge = true;
代替:
using (ExcelRange rng = ws.Cells["A1:C1"])
{
bool merge = rng.Merge;
}
如果要動態合並單元格,還可以使用:
worksheet.Cells[FromRow, FromColumn, ToRow, ToColumn].Merge = true;
所有這些變量都是整數。
您可以創建一個擴展方法:
public static void Merge(this ExcelRangeBase range)
{
ExcelCellAddress start = range.Start;
ExcelCellAddress end = range.End;
range.Worksheet.Cells[start.Row, start.Column, end.Row, end.Column].Merge = true;
}
您可以像通過互操作一樣使用它:
range.Merge();
int initio = CELDA_CUERPO; 布爾值=真;
int COLUMNA_A = 0;
int finx_a = 0;
int finy_a = 0;
int COLUMNA_B = 1;
int finx_b = 0;
int finy_b = 0;
//品塔爾卡貝塞拉:
for (int i = 0; i < ListaCabecera.Length; i++)
{
celda = $"{letras[i]}{CELDA_CABECERA}";
if (i == 0)
{
inicioRango = celda;
}
Sheet.Cells[celda].Value = ListaCabecera[i];
//System.Drawing.Color colFromHex = System.Drawing.ColorTranslator.FromHtml("#B7DEE8");
Sheet.Cells[celda].Style.Font.Color.SetColor(Color.FromArgb(0, 124, 183));
Sheet.Cells[celda].Style.Fill.PatternType = ExcelFillStyle.Solid;
Sheet.Cells[celda].Style.Fill.BackgroundColor.SetColor(Color.FromArgb(232, 235, 249));
Sheet.Cells[celda].Style.Font.Bold = true;
Sheet.Cells[celda].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
}
//Pintar detalle:
for (int i = 0; i < Datos.GetLength(0); i++)
{
for (int j = 0; j < Datos.GetLength(1); j++)
{
celda = $"{letras[j]}{CELDA_CUERPO + i}";
finalizaRango = celda;
if (j < 3) if (Datos[i, j].valor != null && Datos[i, j + 1].valor == null)
{
Sheet.Cells[celda].Style.Font.Color.SetColor(Color.FromArgb(156, 0, 6));
Sheet.Cells[celda].Style.Fill.PatternType = ExcelFillStyle.Solid;
Sheet.Cells[celda].Style.Fill.BackgroundColor.SetColor(Color.FromArgb(255, 199,206));
}
Sheet.Cells[celda].Value = Datos[i, j].valor;
}
