WPF 表列大小 [英] WPF Table Column Sizes

问题描述

我正在渲染一个表格在 WPF FlowDocument 中使用代码隐藏.但是，我一直无法找到一个示例来说明如何使表格仅使用所需的空间基于内容.相反，表格占据了所有可用的宽度，这是我不想要的，我也不想指定确切的像素大小.

I'm rendering a Table in a WPF FlowDocument using code-behind. But, I've been unable to find an example that shows how to make the table use only the space needed based on content. Instead the table takes up all available width, which I don't want, nor do I want to have to specify a exact pixel sizes.

我显然遗漏了一些简单的东西，有人看到了吗?

I'm clearly missing something simple, anyone see it?

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);

推荐答案

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

I do not think this is possible... the only hacky workaround is to use the BlockUIContainer and a real grid!

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));
