WPF Table Colonne Tailles

Question

Je rends un Table dans un WPF FlowDocument en utilisant le code-behind. Mais, j'ai été incapable de trouver un exemple qui montre comment faire que la table utilise seulement l'espace nécessaire based on content. Au lieu de cela, la table prend toute la largeur disponible, ce que je ne veux pas, et je ne veux pas avoir à spécifier une taille de pixel exacte.

Il me manque clairement quelque chose de simple, quelqu'un le voit?

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);

Je ne pense pas que ce soit possible ... la seule solution de contournement hacky est d'utiliser le BlockUIContainer et une grille réelle!

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));

essayer TableCell.ColoumnSpan et TableCell.RowSpan
