Hello stackoverflow社区，

我遇到麻烦让按钮和我的标签正确对齐，我想知道你们是否给我一些帮助！谢谢！

正如您所看到的那样，按钮有点偏离对齐。

代码

// Testing Purposes
        List<Item> headers = TestingClass.getHeaders();

        // Organization of the grid structure
        RowDefinition r1 = new RowDefinition();
        grid_headers.RowDefinitions.Add(r1);

        // Header for Label
        ColumnDefinition cd0 = new ColumnDefinition();
        Label label = new Label();
        label.Content = "Label";
        Grid.SetColumn(label, 0);
        grid_headers.ColumnDefinitions.Add(cd0);
        grid_headers.Children.Add(label);

        // Header for Description
        ColumnDefinition cd1 = new ColumnDefinition();
        Label description = new Label();
        Grid.SetColumn(description, 1);
        description.Content = "Description";
        grid_headers.ColumnDefinitions.Add(cd1);
        grid_headers.Children.Add(description);

        // Header for selection buttons
        ColumnDefinition cd2 = new ColumnDefinition();
        Label selection = new Label();
        Grid.SetColumn(selection, 2);
        selection.Content = "Selction";
        grid_headers.ColumnDefinitions.Add(cd2);
        grid_headers.Children.Add(selection);

        // Loop through all of the headers
        for (int i = 0; i < headers.Count; i++)
        {
            // Create button for choosing the header
            Button btn = new Button();
            btn.Content = "Select";
            btn.Name = headers[i].Label;
            btn.Width = 50;
            btn.Height = 20;
            btn.Padding = new Thickness(0.0, 0.0, 0.0, 0.0);
            btn.Click += selectHeader;

            RowDefinition rd = new RowDefinition();
            grid_headers.RowDefinitions.Add(rd);

            // Header for the labels
            Label label_header = new Label();
            label_header.Content = headers[i].Label;
            Grid.SetColumn(label_header, 0);
            Grid.SetRow(label_header, i+1); // Will always be i + 1 due to the first row for the main labels
            grid_headers.Children.Add(label_header);

            // Headers for the description
            Label description_header = new Label();
            description_header.Content = headers[i].Description;
            Grid.SetColumn(description_header, 1);
            Grid.SetRow(description_header, i + 1); // Will always be i + 1 due to the first row for the main labels
            grid_headers.Children.Add(description_header);

            // Button for selecting which header
            Grid.SetColumn(btn, 2);
            Grid.SetRow(btn, i + 1); // Will always be i + 1 due to the first row for the main labels
            grid_headers.Children.Add(btn);
        }

在我的代码中，我动态生成了网格。
感谢您的帮助，我非常感谢。
