在 Openxml 中冻结窗格和列

Question

我需要帮助。

我有一个使用 OpenXMLWriter 的问题要问。

我目前正在使用下面的代码来创建我的 excel 文件，但我想设置列的宽度并冻结窗格。我该怎么做？

因为我为此编写了以下代码。我不知道为什么不工作。

示例将非常有帮助。欣赏并感谢！

Answer 1

这在过去一直困扰着我。 您必须在数据之前将视图添加到工作表中。你可以试试这样：

public bool ExportData(DataSet ds, string destination, List<Tuple<string, string>> parms)
{
    using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(destination, SpreadsheetDocumentType.Workbook))
    {
        WorkbookPart wbp = spreadsheetDocument.AddWorkbookPart();
        WorksheetPart wsp = wbp.AddNewPart<WorksheetPart>();
        Workbook wb = new Workbook();
        FileVersion fv = new FileVersion();
        fv.ApplicationName = "Microsoft Office Excel";

        #region Freeze Panel

        var freezeRow = parms.Count;
        string freezeRangeFrom = $"A{freezeRow + 2}";

        SheetViews sheetViews = new SheetViews();
        SheetView sheetView = new SheetView()
        {
            TabSelected = false,
            WorkbookViewId = (UInt32Value)0U
        };

        Pane pane = new Pane()
        {
            VerticalSplit = 7D,
            TopLeftCell = freezeRangeFrom,
            ActivePane = PaneValues.BottomLeft,
            State = PaneStateValues.Frozen
        };

        sheetView.Append(pane);

        #endregion

        Worksheet worksheet = new Worksheet(new SheetViews(sheetView));
        SheetData sheetData = new SheetData();


        foreach (DataTable table in ds.Tables)
        {
            Row headerRow = new Row();

            foreach (var parm in parms)
            {
                Row newRow = new Row();

                // Write the parameter names
                Cell parmNameCell = new Cell();
                parmNameCell.DataType = CellValues.String;
                parmNameCell.CellValue = new CellValue(parm.Item1.ToString()); //
                parmNameCell.StyleIndex = 1;

                newRow.AppendChild(parmNameCell);

                // Write the parameter values

                Cell parmValCell = new Cell();
                parmValCell.DataType = CellValues.InlineString;
                parmValCell.DataType = CellValues.String;
                parmValCell.CellValue = new CellValue(parm.Item2?.ToString()); //
                newRow.AppendChild(parmValCell);

                sheetData.AppendChild(newRow);
            }

            Columns columns = new Columns();
            int i = 1;
            foreach (DataColumn column in table.Columns)
            {
                Column column1 = new Column();
                column1.Min = Convert.ToUInt32(i);
                column1.Max = Convert.ToUInt32(i);
                column1.Width = insertSpaceBeforeUpperCAse(column.ColumnName).Length + 2;
                column1.BestFit = true;
                columns.Append(column1);
                i++;
            }
            worksheet.Append(columns);

            Row blankRow = new Row();
            sheetData.AppendChild(blankRow);

            //// Write the column names
            List<string> columns2 = new List<string>();
            foreach (DataColumn column in table.Columns)
            {
                columns2.Add(column.ColumnName);

                Cell cell = new Cell();
                cell.DataType = CellValues.String;
                cell.CellValue = new CellValue(insertSpaceBeforeUpperCAse(column.ColumnName));

                cell.StyleIndex = 1;
                headerRow.AppendChild(cell);
            }

            sheetData.AppendChild(headerRow);

            foreach (DataRow dsrow in table.Rows)
            {
                Row newRow = new Row();
                foreach (string col in columns2)
                {
                    Cell cell = new Cell();
                    cell.DataType = CellValues.String;
                    cell.CellValue = new CellValue(dsrow[col].ToString()); //
                    newRow.AppendChild(cell);
                }

                sheetData.AppendChild(newRow);
            }

            //worksheet.Append(sheetData);
            //wsp.Worksheet = worksheet;
            //wsp.Worksheet.Save();

            Sheets sheets = new Sheets();
            Sheet sheet = new Sheet();
            sheet.Name = table.TableName;
            sheet.SheetId = 1;
            sheet.Id = wbp.GetIdOfPart(wsp);

            sheets.Append(sheet);
            wb.Append(fv);
            wb.Append(sheets);
        }
        spreadsheetDocument.WorkbookPart.Workbook = wb;
        spreadsheetDocument.WorkbookPart.Workbook.Save();
        spreadsheetDocument.Close();

    }

    return true;
}

如果您的 SheetView 不起作用，我提供了一个对我有用的示例：

        SheetView sheetView = new SheetView() { TabSelected = true, WorkbookViewId = (UInt32Value)0U };
        Pane pane = new Pane() { VerticalSplit = 1D, TopLeftCell = "A2", ActivePane = PaneValues.BottomLeft, State = PaneStateValues.Frozen };
        Selection selection = new Selection() { Pane = PaneValues.BottomLeft, ActiveCell = "A2", SequenceOfReferences = new ListValue<StringValue>() { InnerText = "A2:XFD2" } };
        sheetView.Append(pane);
        sheetView.Append(selection);

Answer 2

这是一个如何冻结第一列的示例。

var sheetViews = new SheetViews();
var sheetView = new SheetView() { TabSelected = true, WorkbookViewId = (UInt32Value)0U };
var pane = new Pane() { ActivePane = PaneValues.TopRight, HorizontalSplit = 1D, State = PaneStateValues.Frozen, TopLeftCell = "B1" };
var selection = new Selection() { Pane = PaneValues.TopRight };
sheetView.Append(pane);
sheetView.Append(selection);
sheetViews.Append(sheetView);
