如何:以编程方式生成表
以下示例演示如何以编程方式创建 Table 并填充内容。 表格内容分为五行(由 RowGroups 对象中包含的 TableRow 对象表示)和六列(由 TableColumn 对象表示)。 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的数据列,而页脚行则包含摘要信息。 请注意,“标题”行、“标头”行和“页脚”行并非表格所固有的,它们只是具有不同特征的行。 表单元格包含实际内容,可以包含文本、图像或几乎任何其他用户界面 (UI) 元素。
创建表
首先,创建一个 FlowDocument 来承载 Table,然后创建一个新的 Table 并将其添加到 FlowDocument 的内容中。
// 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
添加列
接下来,创建六个 TableColumn 对象并将其添加到表的 Columns 集合中,然后应用一些格式。
注意
请注意,表格的 Columns 集合使用标准的从零开始的索引。
// 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;
}
' 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
添加标题行
接下来,创建一个标题行,并将其添加到表中,同时应用某些格式设置。 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.
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.
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
添加标头行
接下来,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"))))
添加行
接下来,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
添加页脚行
最后,创建、添加脚注行并设置其格式。 与标题行类似,脚注包含的单元格的跨度为表中的全部六列。
table1.RowGroups[0].Rows.Add(new TableRow());
currentRow = table1.RowGroups[0].Rows[3];
// 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(3)
' 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
