已修复的记录：创建的工作表中的单元格信息

Question

我在打开 OpenXML 创建的电子表格时收到错误消息。报错如下

repaired record : xl/worksheets/sheet.xml partial cell information

private void SavexlsExcelFile(String fullPathName)
    {
        using (SpreadsheetDocument document = SpreadsheetDocument.Create(fullPathName, SpreadsheetDocumentType.Workbook))
        {

            WorkbookPart workbookPart = document.AddWorkbookPart();
            workbookPart.Workbook = new Workbook();

            worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
            worksheetPart.Worksheet = new Worksheet();

            Columns columns = new Columns();

            worksheetPart.Worksheet.AppendChild(columns);

            Sheets sheets = workbookPart.Workbook.AppendChild(new Sheets());

            Sheet sheet = new Sheet() { Id = workbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Sheet" };
            sheets.Append(sheet);

            workbookPart.Workbook.Save();

            sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());


            List<List<string>> dataRow = new List<List<string>>();
            List<String> dtRow = new List<String>();

            Row row = new Row();

            for (int i = 0; i < dataGridView1.RowCount; i++)
            {
                for (int j = 0; j < dataGridView1.ColumnCount; j++)
                {
                    if (i == 0)
                    {
                        Cell dataCell = new Cell();
                        dataCell.DataType = CellValues.String;
                        CellValue cellValue = new CellValue();

                        cellValue.Text = dataGridView1.Columns[j].Name;
                        dataCell.StyleIndex = 2;
                        dataCell.Append(cellValue);
                        row.AppendChild(dataCell);
                        //dataColumn.Add(dataGridView1.Columns[j].Name);
                    }
                    dtRow.Add(dataGridView1.Rows[i].Cells[j].Value.ToString());
                }
            }

            dataRow.Add(dtRow);
            sheetData.AppendChild(row);

            row = new Row();

            foreach (List<string> datarow in dataRow)
            {
                row = new Row();
                foreach(string dtrow in datarow)
                {
                    row.Append(ConstructCell(dtrow, CellValues.String, 2));
                }
                sheetData.AppendChild(row);
            }
            worksheetPart.Worksheet.Save();
        }
    }
    private Cell ConstructCell(string value, CellValues dataType, uint styleIndex = 0)
    {
        return new Cell()
        {
            CellValue = new CellValue(value),
            DataType = new EnumValue<CellValues>(dataType),
            StyleIndex = styleIndex
        };
    }

Answer 1

Excel 中的所有文本都存储在共享字符串 table 下。您需要将字符串插入共享字符串 table:

string text = dataGridView1.Columns[j].Name; 
cell.DataType = CellValues.SharedString;

if (!_spreadSheet.WorkbookPart.GetPartsOfType<SharedStringTablePart>().Any())
{
    _spreadSheet.WorkbookPart.AddNewPart<SharedStringTablePart>();
}

var sharedStringTablePart = _spreadSheet.WorkbookPart.GetPartsOfType<SharedStringTablePart>().First();
if (sharedStringTablePart.SharedStringTable == null)
{
    sharedStringTablePart.SharedStringTable = new SharedStringTable();
}
//Iterate through shared string table to check if the value is already present.
foreach (SharedStringItem ssItem in sharedStringTablePart.SharedStringTable.Elements<SharedStringItem>())
{
    if (ssItem.InnerText == text)
    {
        cell.CellValue = new CellValue(ssItem.ElementsBefore().Count().ToString());
        SaveChanges();
        return;
    }
}
// The text does not exist in the part. Create the SharedStringItem.
var item = sharedStringTablePart.SharedStringTable.AppendChild(new SharedStringItem(new Text(text)));
cell.CellValue = new CellValue(item.ElementsBefore().Count().ToString());

Answer 2

我在这里看到了 2 个问题。首先是您对 Columns 的使用不正确。如果你想控制诸如列宽之类的东西，你应该使用 Columns。要正确使用 Columns，您需要添加子 Column 元素。例如（取自）：

Columns columns = new Columns();

columns.Append(new Column() { Min = 1, Max = 3, Width = 20, CustomWidth = true });
columns.Append(new Column() { Min = 4, Max = 4, Width = 30, CustomWidth = true });

在您的示例中，您可以删除以下两行

Columns columns = new Columns();
worksheetPart.Worksheet.AppendChild(columns);

第二个问题是您正在使用的StyleIndex；该样式在您的文档中不存在，因为您尚未添加它。此处最简单的做法是完全删除 StyleIndex。

像这样调试文件时，OpenXml Productivity Tool 总是值得一看的。您可以在该工具中打开生成的文件并对其进行验证，以查看文件中存在哪些错误。
