【问题描述】:
在 C# 中将多个 Excel 工作表合并到一个 Excel 文档时遇到问题。所以本质上它是一个包含多张工作表的工作簿。但是,这有效
问题在于它没有保留格式和样式。第一张表格的格式正确,但是它在整个表格中复制了不应该的相同样式。
我在合并工作表和保持相同的样式和格式方面需要帮助。
循环遍历工作表 C#
// For each worksheet in the child workbook...
foreach (Sheet childSheet in childWorkbookSheets)
{
// Get a worksheet part for the child worksheet using
// it's relationship Id.
childWorksheetPart = (WorksheetPart)childWorkbook.WorkbookPart.GetPartById(childSheet.Id);
// Add a worksheet part to the merged workbook based on
// the child worksheet.
mergedWorksheetPart = mergedWorkbookPart.AddPart<WorksheetPart>(childWorksheetPart);
//There should be only one worksheet that is set
//as the main view.
CleanView(mergedWorksheetPart);
// Create a Sheet element for the new sheet in the
// merged workbook.
newMergedSheet = new Sheet();
// Set the Name, Id, and SheetId attributes of the
// new Sheet element.
newMergedSheet.Name = GenerateWorksheetName(mergedWorkbookSheets, childSheet.Name.Value);
newMergedSheet.Id = mergedWorkbookPart.GetIdOfPart(mergedWorksheetPart);
newMergedSheet.SheetId = (uint)mergedWorkbookSheets.ChildElements.Count + 1;
// Add the new Sheet element to the Sheets element in the
// merged workbook.
mergedWorkbookSheets.Append(newMergedSheet);
// Get the SheetData element of the new worksheet part
// in the merged workbook.
mergedSheetData = mergedWorksheetPart.Worksheet.GetFirstChild<SheetData>();
if (styleCounter == 0)
{
mergedWorkbook.WorkbookPart.AddPart<WorkbookStylesPart>(childSharedStylePart);
}
styleCounter++;
// For each row of data...
foreach (Row row in mergedSheetData.Elements<Row>())
{
// For each cell in the row...
foreach (Cell cell in row.Elements<Cell>())
{
// If the cell is using a shared string, merge
// the string from the child workbook into the merged
// workbook.
CellFormat cellFormat = cell.StyleIndex != null ? GetCellFormat(mergedWorkbookPart, cell.StyleIndex).CloneNode(true) as CellFormat : new CellFormat();
GetCellFormat(mergedWorkbookPart, cell.StyleIndex);
if (cell.DataType != null &&
cell.DataType.Value == CellValues.SharedString)
{
ProcessCellSharedString(mergedWorksheetPart, cell, mergedSharedStringTablePart, childSharedStringTablePart);
}
cell.StyleIndex = InsertCellFormat(mergedWorkbookPart, cellFormat);
mergedSheetData.AppendChild(new Cell());
mergedCellformat = GetCellFormat(mergedWorkbookPart, cell.StyleIndex);
//cellFormat.ReplaceChild(mergedCellformat,mergedCellformat);
//attempt to add styling to the other worksheets
mergedCellformat.FillId.Value = (cellFormat.FillId.Value);
mergedCellformat.BorderId.Value = (cellFormat.BorderId.Value);
mergedCellformat.FontId.Value = (cellFormat.FontId.Value);
//mergedCellformat.FormatId = (cellFormat.FormatId.Value);
//cellFormat.AppendChild(mergedCellformat);
//cellFormat.Append(mergedCellformat);
}
}
第一张纸很完美,它保留了格式和正确性。 其余的表格到处都是它的格式。不一样。
private static CellFormat GetCellFormat(WorkbookPart workbookPart, uint styleIndex)
{
return workbookPart.WorkbookStylesPart.Stylesheet.Elements<CellFormats>().First().Elements<CellFormat>().ElementAt((int)styleIndex);
}
private static uint InsertCellFormat(WorkbookPart workbookPart, CellFormat cellFormat)
{
CellFormats cellFormats = workbookPart.WorkbookStylesPart.Stylesheet.Elements<CellFormats>().First();
cellFormats.Append(cellFormat);
return (uint)cellFormats.Count++;
}
【问题讨论】:
-
任何时候格式化都是拼图的关键部分,图片是值得赞赏的。您能否添加一些当前(错误)行为和预期行为的图像?
-
@Mikegrann 嗨,第一张图片显示了工作表的第一张。它保留相同的格式并且很好。但是其他工作表不是,格式不正确并且没有被保留。
-
你能展示你的
GetCellFormat和InsertCellFormat方法吗? -
@petelids 我已将它们添加到上面的代码中
-
我怀疑这是您的(整个)问题,但
return (uint)cellFormats.Count++;对我来说看起来不对。这将返回Count,然后在返回它之后增加计数。这是故意的吗?
