尝试在使用 openXML 生成 word 文档时合并表格单元格

Question

我正在尝试生成一个word文档，其中创建的表格如图像中所述，下面的代码将合并第四列中的单元格以制作表格。

当我合并单元格时，不知何故添加了一个额外的空间，如图所示。

var rowHeaderLabels = new List<string> { "Space", "Lighting Density" };                       
var columnHeaderLabels = new List<string> { "Occupants per 1000sf", "Sensible BTUH", "Latent BTUH" };
var assumedLoadsTable = RenderTableWithMergedHeader(rowHeaderLabels, "Equipment Density", "Occupant", columnHeaderLabels, assumedHeatingAndCoolingData);

这是RenderTableWithMergedHeader方法的代码

 private static Table RenderTableWithMergedHeader(List<string> rowsHeaderLabel,string lastColumnName,string mergedColumnLabel, List<string> columnsHeaderLabel, List<List<string>> contentData)
    {
        var table = new Table();
        var tableProperties = RenderTableProperties();
        table.AppendChild(tableProperties);

        TableRow tableHeaderRowA = new TableRow();
        TableRow tableHeaderRowB = new TableRow();

        foreach (var colName in rowsHeaderLabel)
        {
            tableHeaderRowA.Append(RenderTableHeaderCell(colName));
        }
        table.Append(tableHeaderRowA);
        // problem is here with tableHeaderRowA
        tableHeaderRowA.Append(RenderTableHeaderCell(lastColumnName, 1, MergedCellValues.Restart));
        tableHeaderRowB.Append(RenderTableHeaderCell(null, 3, MergedCellValues.Continue));

        tableHeaderRowA.Append(RenderTableHeaderCell(mergedColumnLabel,columnsHeaderLabel.Count));
        foreach (var colName in columnsHeaderLabel)
        {
            tableHeaderRowB.Append(RenderTableHeaderCell(colName));
        }
        table.Append(tableHeaderRowB);
        // Content binding code
        return table;
    }

这是RenderTableHeaderCell方法的代码

    public static TableCell RenderTableHeaderCell(string columnName, int horizontalSpan = 1, MergedCellValues? verticalMerge = null)
    {
        TableCell tableCell = new TableCell();
        TableCellVerticalAlignment tableCellVerticalAlignment = new TableCellVerticalAlignment() { Val = TableVerticalAlignmentValues.Center };
        Paragraph paragraph = new Paragraph();
        TableCellProperties tableCellProperties = RenderTablecellProperties();
        tableCellProperties.Append(tableCellVerticalAlignment);
        if (horizontalSpan != 1)
        {
            tableCellProperties.Append(new GridSpan() { Val = horizontalSpan });
        }
        if (verticalMerge != null)
        {
            VerticalMerge vm = new VerticalMerge() { Val = verticalMerge };
            tableCellProperties.Append(vm);
        }
        var paragraphProperties = RenderParagraphJustification();
        paragraph.Append(paragraphProperties);
        Run newChild = RenderRun(columnName);
        paragraph.AppendChild(newChild);
        tableCell.Append(tableCellProperties);
        tableCell.Append(paragraph);

        return tableCell;
    }

这正在生成如下图所示的表格

我正在寻找如下图所示的表格

我不确定上面的代码在哪里做错了，任何人都可以提出有关如何删除第一张图像中显示的空间的任何想法。

提前谢谢了

我通过修改以下方法解决了我的问题

  private static Table RenderTableWithMergedHeader(List<string> rowsHeaderLabel, string mergedColumnName, List<string> columnsHeaderLabel, List<List<string>> contentData)
  {
        var table = new Table();
        var tableProperties = RenderTableProperties();
        table.AppendChild(tableProperties);

        TableRow tableHeaderRowA = new TableRow();
        TableRow tableHeaderRowB = new TableRow();

        foreach (var colName in rowsHeaderLabel)
        {
            tableHeaderRowA.Append(RenderTableHeaderCell(colName, 1, MergedCellValues.Restart));
            tableHeaderRowB.Append(RenderTableHeaderCell(null, 1, MergedCellValues.Continue));
        }
        tableHeaderRowA.Append(RenderTableHeaderCell(mergedColumnName, columnsHeaderLabel.Count));

        foreach (var colName in columnsHeaderLabel)
        {
            tableHeaderRowB.Append(RenderTableHeaderCell(colName));
        }

        table.Append(tableHeaderRowA);
        table.Append(tableHeaderRowB);
        foreach (var rowData in contentData)
        {
            var row = new TableRow();
            foreach (var cellData in rowData)
            {
                row.Append(RenderContentCell(cellData));
            }
            table.Append(row);
        }

        return table;
  }
