减少白色空间行 [英] Reduce White Space Row

问题描述

目标：

在richtextbox顶部的行中减少空白区域。我有列名但它不可见。列名称占用了richtextbox顶部的空格。我想删除列名以减少空间。



问题：

它有空格行的原因是由于无形的专栏名称，我想知道我该怎样做才能满足目标？

Goal:
Less white space in the row on the top of the richtextbox. I have column name but it is not visible. Column name takes space in the top of richtextbox. I want to remove the column name in order to reduce space.

Problem:
The reason why it has white space row is due to invisibly column name and I wonder how should I do in order to fullfill the goal?

private void btn_test_Click(object sender, RoutedEventArgs e)
  {
   Table table = newRtb.FindName("MyTable") as Table;
   foreach (TableRow row in table.RowGroups[0].Rows)
   {
    if (row.Background == Brushes.SpringGreen)
    {
     //get value of third cell:
     BlockUIContainer container = row.Cells[2].Blocks.ElementAt(0) as BlockUIContainer;
     TextBlock textBlock = container.Child as TextBlock;
     MessageBox.Show(textBlock.Text);
    }
   }
  }

private void MainWindow_Loaded(object sender, RoutedEventArgs e)
  {
   var tab = new Table();
   tab.Name = "MyTable";
   newRtb.RegisterName("MyTable", tab);


   var gridLenghtConvertor = new GridLengthConverter();

   tab.Columns.Add(new TableColumn() { Name = "Column1", Width = (GridLength)gridLenghtConvertor.ConvertFromString("*") });
   tab.Columns.Add(new TableColumn() { Name = "Column2", Width = (GridLength)gridLenghtConvertor.ConvertFromString("*") });
   tab.Columns.Add(new TableColumn() { Name = "Column3", Width = new GridLength(0) });

   tab.RowGroups.Add(new TableRowGroup());

   for (int i = 0; i < 10; i++)
   {
    TableRow tr = new TableRow();
    tr.MouseLeftButtonDown += tr_MouseLeftButtonDown;
    tab.RowGroups[0].Rows.Add(tr);
    var tabRow = tab.RowGroups[0].Rows[i];

    tabRow.Cells.Add(new TableCell(new Paragraph(new Run("Row" + (i + 1).ToString() + " Column1"))) { TextAlignment = TextAlignment.Center });
    tabRow.Cells.Add(new TableCell(new Paragraph(new Run("Row" + (i + 1).ToString() + " Column2"))));

    BlockUIContainer container = new BlockUIContainer();
    container.Child = new TextBlock(){ Text = "Test"};
    tabRow.Cells.Add(new TableCell(container));
   }


   newRtb.Document.Blocks.Add(tab);

  }
