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 并使用内容填充它。 表的内容分为五行(由 RowGroups 对象中包含的 TableRow 对象表示)和六列(由 TableColumn 对象表示)。 这些行用于不同的呈现目的,包括用于标题整个表的标题行、用于描述表中数据的列的标题行,以及包含摘要信息的页脚行。 请注意,“标题”、“页眉”和“页脚”行的概念不是表格固有的,这些只是具有不同特征的行。 表格单元格包含实际内容,这些内容可以由文本、图像或几乎任何其他用户界面 (UI) 元素组成。

创建表

首先,创建一个 FlowDocument 来托管 Table,并创建一个新的 Table 并将其添加到 FlowDocument的内容。

// 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,将创建六个 TableColumn 对象并将其添加到表的 Columns 集合中,并应用了一些格式。

备注

请注意,表的 Columns 集合使用标准从零开始的索引。

// 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,将创建标题行并将其添加到已应用某些格式的表格中。 标题行恰好包含一个跨表中所有六列的单元格。

// 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

添加标题行

接下来,将创建标题行并将其添加到表中,并创建标题行中的单元格并填充内容。

// 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,将创建数据行并将其添加到表中,并创建此行中的单元格并填充内容。 生成此行类似于生成标题行,应用的格式略有不同。

// 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。 与标题行一样,页脚包含一个跨表格中所有六列的单元格。

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
