WPF表列大小

Question

我使用代码隐藏在WPF FlowDocument中呈现Table。但是，我一直无法找到一个例子，说明如何让桌子只使用需要的空间based on content。相反，表占用了所有可用的宽度，我不想要，也不想指定确切的像素大小。

我很明显缺少一些简单的东西，有人看到它？

var fd = new FlowDocument(); 

Table t = new Table(); 

t.BorderBrush = Brushes.Black; 
t.BorderThickness = new Thickness(2); 

// I thought this would do what I wanted... 
t.Columns.Add(new TableColumn() { Width = GridLength.Auto }); 
t.Columns.Add(new TableCOlumn() { Width = GridLength.Auto }); 

TableRowGroup trg = new TableRowGroup(); 

TableRow currentRow = new TableRow(); 
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("ABC")))); 
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("XYZ")))); 
trg.Rows.Add(currentRow); 

currentRow = new TableRow(); 
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("123")))); 
currentRow.Cells.Add(new TableCell(new Paragraph(new Run("789")))); 
trg.Rows.Add(currentRow); 

t.RowGroups.Add(trg); 

fd.Blocks.Add(t);

我不认为这是可能的...唯一的hacky解决方法是使用BlockUIContainer和一个真正的网格！

var fd = new FlowDocument(); 

Grid g = new Grid(); 

g.ColumnDefinitions.Add(new ColumnDefinition() { Width = GridLength.Auto }); 
g.ColumnDefinitions.Add(new ColumnDefinition() { Width = GridLength.Auto }); 

g.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto }); 
g.RowDefinitions.Add(new RowDefinition() { Height = GridLength.Auto }); 

var t1 = new TextBlock() { Text = "ABC", Margin = new Thickness(5,3,5,3) }; 
t1.SetValue(Grid.ColumnProperty, 0); 
t1.SetValue(Grid.RowProperty, 0); 
g.Children.Add(t1); 

var t2 = new TextBlock() { Text = "XYZ", Margin = new Thickness(5, 3, 5, 3) }; 
t2.SetValue(Grid.ColumnProperty, 1); 
t2.SetValue(Grid.RowProperty, 0); 
g.Children.Add(t2); 

var t3 = new TextBlock() { Text = "123", Margin = new Thickness(5, 3, 5, 3) }; 
t3.SetValue(Grid.ColumnProperty, 0); 
t3.SetValue(Grid.RowProperty, 1); 
g.Children.Add(t3); 

var t4 = new TextBlock() { Text = "789", Margin = new Thickness(5, 3, 5, 3) }; 
t4.SetValue(Grid.ColumnProperty, 1); 
t4.SetValue(Grid.RowProperty, 1); 
g.Children.Add(t4); 

fd.Blocks.Add(new BlockUIContainer(g));

尝试TableCell.ColoumnSpan和TableCell.RowSpan
