如何：以编程方式生成表
更新：2007 年 11 月
以下示例演示如何以编程方式创建 Table 和填充其内容。该表的内容分配到五个行（由 RowGroups 对象中包含的 TableRow 对象表示）和六个列（由 TableColumn 对象表示）中。各行用于不同的显示目的，其中，标题行用于显示整个表的标题，标头行用于描述表中数据的列，而脚注行则包含摘要信息。 请注意，“标题”、“标头”和“脚注”行并非表所固有的，它们只是具有不同特征的行。表单元格包含实际内容，可以包括文本、图像或任何其他用户界面 (UI) 元素。

示例
首先，创建一个 FlowDocument 以承载 Table，并创建一个新的 Table，同时将其添加到 FlowDocument 内容中。
' Create the parent FlowDocument...
flowDoc = New FlowDocument()
' Create the Table...
table1 = New Table()
' ...and add it to the FlowDocument Blocks collection.
flowDoc.Blocks.Add(table1)
' Set some global formatting properties for the table.
table1.CellSpacing = 10
table1.Background = Brushes.White
// Create the parent FlowDocument...
flowDoc = new FlowDocument();
// Create the Table...
table1 = new Table();
// ...and add it to the FlowDocument Blocks collection.
flowDoc.Blocks.Add(table1);
// Set some global formatting properties for the table.
table1.CellSpacing = 10;
table1.Background = Brushes.White;
然后，创建六个 TableColumn 对象，并将它们添加到表的 Columns 集合中，同时应用某些格式设置。
| 说明： |
|---|
请注意，表的 Columns 集合使用从零开始的标准索引。 |
' Create 6 columns and add them to the table's Columns collection.
Dim numberOfColumns = 6
Dim x
For x = 0 To numberOfColumns
table1.Columns.Add(new TableColumn())
' Set alternating background colors for the middle colums.
If x Mod 2 = 0 Then
table1.Columns(x).Background = Brushes.Beige
Else
table1.Columns(x).Background = Brushes.LightSteelBlue
End If
Next x
// Create 6 columns and add them to the table's Columns collection.
int numberOfColumns = 6;
for (int x = 0; x < numberOfColumns; x++)
{
table1.Columns.Add(new TableColumn());
// Set alternating background colors for the middle colums.
if(x%2 == 0)
table1.Columns[x].Background = Brushes.Beige;
else
table1.Columns[x].Background = Brushes.LightSteelBlue;
}
然后，创建一个标题行，并将其添加到表中，同时应用一些格式设置。 标题行包含一个单元格，该单元格跨表中的全部六列。
' Create and add an empty TableRowGroup to hold the table's Rows.
table1.RowGroups.Add(new TableRowGroup())
' Add the first (title) row.
table1.RowGroups(0).Rows.Add(new TableRow())
' Alias the current working row for easy reference.
Dim currentRow As New TableRow()
currentRow = table1.RowGroups(0).Rows(0)
' Global formatting for the title row.
currentRow.Background = Brushes.Silver
currentRow.FontSize = 40
currentRow.FontWeight = System.Windows.FontWeights.Bold
' Add the header row with content,
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("2004 Sales Project"))))
' and set the row to span all 6 columns.
currentRow.Cells(0).ColumnSpan = 6
// Create and add an empty TableRowGroup to hold the table's Rows.
table1.RowGroups.Add(new TableRowGroup());
// Add the first (title) row.
table1.RowGroups[0].Rows.Add(new TableRow());
// Alias the current working row for easy reference.
TableRow currentRow = table1.RowGroups[0].Rows[0];
// Global formatting for the title row.
currentRow.Background = Brushes.Silver;
currentRow.FontSize = 40;
currentRow.FontWeight = System.Windows.FontWeights.Bold;
// Add the header row with content,
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("2004 Sales Project"))));
// and set the row to span all 6 columns.
currentRow.Cells[0].ColumnSpan = 6;
然后，创建一个标头行并将其添加到表中，同时创建标头行中的单元格并填充其内容。
' Add the second (header) row.
table1.RowGroups(0).Rows.Add(new TableRow())
currentRow = table1.RowGroups(0).Rows(1)
' Global formatting for the header row.
currentRow.FontSize = 18
currentRow.FontWeight = FontWeights.Bold
' Add cells with content to the second row.
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Product"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 1"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 2"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 3"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 4"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("TOTAL"))))
// Add the second (header) row.
table1.RowGroups[0].Rows.Add(new TableRow());
currentRow = table1.RowGroups[0].Rows[1];
// Global formatting for the header row.
currentRow.FontSize = 18;
currentRow.FontWeight = FontWeights.Bold;
// Add cells with content to the second row.
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Product"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 1"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 2"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 3"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Quarter 4"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("TOTAL"))));
然后，创建一个数据行并将其添加到表中，同时创建此行中的单元格并填充其内容。 生成此行的过程与生成标头行的过程类似，只是应用的格式设置略有不同。
' Add the third row.
table1.RowGroups(0).Rows.Add(new TableRow())
currentRow = table1.RowGroups(0).Rows(2)
' Global formatting for the row.
currentRow.FontSize = 12
currentRow.FontWeight = FontWeights.Normal
' Add cells with content to the third row.
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Widgets"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$50,000"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$55,000"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$60,000"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$65,000"))))
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$230,000"))))
' Bold the first cell.
currentRow.Cells(0).FontWeight = FontWeights.Bold
// Add the third row.
table1.RowGroups[0].Rows.Add(new TableRow());
currentRow = table1.RowGroups[0].Rows[2];
// Global formatting for the row.
currentRow.FontSize = 12;
currentRow.FontWeight = FontWeights.Normal;
// Add cells with content to the third row.
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Widgets"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$50,000"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$55,000"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$60,000"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$65,000"))));
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("$230,000"))));
// Bold the first cell.
currentRow.Cells[0].FontWeight = FontWeights.Bold;
最后，创建、添加脚注行并设置其格式。 与标题行类似，该脚注包含一个跨表中全部六列的单元格。
table1.RowGroups(0).Rows.Add(new TableRow())
currentRow = table1.RowGroups(0).Rows(4)
' Global formatting for the footer row.
currentRow.Background = Brushes.LightGray
currentRow.FontSize = 18
currentRow.FontWeight = System.Windows.FontWeights.Normal
' Add the header row with content,
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Projected 2004 Revenue: $810,000"))))
' and set the row to span all 6 columns.
currentRow.Cells(0).ColumnSpan = 6
table1.RowGroups[0].Rows.Add(new TableRow());
currentRow = table1.RowGroups[0].Rows[4];
// Global formatting for the footer row.
currentRow.Background = Brushes.LightGray;
currentRow.FontSize = 18;
currentRow.FontWeight = System.Windows.FontWeights.Normal;
// Add the header row with content,
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("Projected 2004 Revenue: $810,000"))));
// and set the row to span all 6 columns.
currentRow.Cells[0].ColumnSpan = 6;
