wpf - WPF表列大小

Question

我正在使用代码隐藏在WPF Table中渲染FlowDocument。但是，我一直找不到一个示例，该示例演示如何使表仅使用所需的based on content空间。相反，表格占据了所有不需要的宽度，我也不需要，也不必指定确切的像素大小。

我显然缺少简单的东西，有人看到吗？

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);

我认为这是不可能的...唯一的解决方法是使用BlockUIContainer和真实的网格！

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));
