将Epplus Excel中的合并单元格转换为HTML

我正在使用Epplus将Excel电子表格转换为HTML。 到目前为止，事情非常非常好，除了一件事：跨越合并的单元格。 我似乎无法得到正确的逻辑。 我想我会把它扔到那里，看看社区将如何处理它。 这是我的代码到目前为止。

public String ParseExcelStamps(String FileName) { FileInfo theFile = new FileInfo(FileName); String html = ""; using (ExcelPackage xlPackage = new ExcelPackage(theFile)) { var workbook = xlPackage.Workbook; if (workbook != null) { for (int j = 1; j <= workbook.Worksheets.Count; j++) { Tab tab = new Tab(); html+= "<table style='border-collapse: collapse;font-family:arial;'><tbody>"; var worksheet = workbook.Worksheets[j]; tab.Title = worksheet.Name; if (worksheet.Dimension == null) { continue; } int rowCount = 0; int maxColumnNumber = worksheet.Dimension.End.Column; var convertedRecords = new List<List<string>>(worksheet.Dimension.End.Row); var excelRows = worksheet.Cells.GroupBy(c => c.Start.Row).ToList(); excelRows.ForEach(r => { rowCount++; html += String.Format("<tr>"); var currentRecord = new List<string>(maxColumnNumber); var cells = r.OrderBy(cell => cell.Start.Column).ToList(); Double rowHeight = worksheet.Row(rowCount).Height; for (int i = 1; i <= maxColumnNumber; i++) { var currentCell = cells.Where(c => c.Start.Column == i).FirstOrDefault(); //look aheads for colspan and rowspan ExcelRangeBase previousCellAbove = null; ExcelRangeBase previousCell = null; ExcelRangeBase nextCell = null; ExcelRangeBase nextCellBelow = null; try { previousCellAbove = worksheet.Cells[rowCount-1, i]; }catch (Exception) { } try { previousCell = worksheet.Cells[rowCount, (i - 1)]; }catch (Exception) { } try { nextCell = worksheet.Cells[rowCount, (i + 1)]; }catch (Exception) { } try { nextCellBelow = worksheet.Cells[rowCount+1, i]; }catch (Exception) { } if ((previousCell != null) && (previousCell.Merge) && (currentCell != null) && (currentCell.Merge)){continue;} if ((previousCellAbove != null) && (previousCellAbove.Merge) && (currentCell != null)) {continue; } if (currentCell == null) { html += String.Format("<td>{0}</td>", String.Empty); } else { int colSpan = 1; int rowSpan = 1; if ((nextCell != null) && (nextCell.Merge) && (currentCell.Merge)) { colSpan = 2; // Console.WriteLine(String.Format("{0} - {1}", currentCell.Address, nextCell.Address)); } if ((nextCellBelow != null) && (nextCellBelow.Merge) && (currentCell.Merge)) { Console.WriteLine(String.Format("{0} - {1}", currentCell.Address, nextCellBelow.Address)); } html += String.Format("<td colspan={0} rowspan={1}>{2}</td>", colSpan, rowSpan, currentCell.Value); } } html += String.Format("</tr>"); }); html += "</tbody></table>"; }//worksheet loop } } return html; }

据我所知，这正是你所需要的。 您所缺less的是工作表上的MergedCells属性，其中列出了工作表中所有合并的单元格。

我的代码同时处理行跨度，列跨度和两者。 我用包含行，列和行/列跨度的电子表格做了一些testing。 在所有情况下，他们完美的工作

码

 int colSpan = 1; int rowSpan = 1; //check if this is the start of a merged cell ExcelAddress cellAddress = new ExcelAddress(currentCell.Address); var mCellsResult = (from c in worksheet.MergedCells let addr = new ExcelAddress(c) where cellAddress.Start.Row >= addr.Start.Row && cellAddress.End.Row <= addr.End.Row && cellAddress.Start.Column >= addr.Start.Column && cellAddress.End.Column <= addr.End.Column select addr); if (mCellsResult.Count() >0) { var mCells = mCellsResult.First(); //if the cell and the merged cell do not share a common start address then skip this cell as it's already been covered by a previous item if (mCells.Start.Address != cellAddress.Start.Address) continue; if(mCells.Start.Column != mCells.End.Column) { colSpan += mCells.End.Column - mCells.Start.Column; } if (mCells.Start.Row != mCells.End.Row) { rowSpan += mCells.End.Row - mCells.Start.Row; } } //load up data html += String.Format("<td colspan={0} rowspan={1}>{2}</td>", colSpan, rowSpan, currentCell.Value);
