c# - 为什么我在 tablelayoutpanel 中有垂直滚动条

Question

我正在尝试动态创建一个按钮并将它们添加到表格布局面板，问题是无论我做什么，即使我只有一排按钮，我也会一直有一个垂直滚动条。代码:

 private void button2_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < 50; i++)
        {
            Button button = new Button();
         //   button.Location = new Point(20, 30 * i + 10);
        button.Click += new EventHandler(ButtonClick);
        this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Absolute, 20F));
        tableLayoutPanel1.ColumnCount += 1;
        tableLayoutPanel1.Controls.Add(button);
        }
    }

结果:

我想去掉横的就可以了

尝试将水平滚动条的高度添加到控件的填充中:

private void button2_Click(object sender, EventArgs e)
{
  tableLayoutPanel1.Padding = new Padding(0, 0, 0, SystemInformation.HorizontalScrollBarHeight);

  for (int i = 0; i < 50; i++)
  {
    Button button = new Button();
    button.Click += new EventHandler(ButtonClick);
    tableLayoutPanel1.ColumnStyles.Add(new ColumnStyle(SizeType.Absolute, 20F));
    tableLayoutPanel1.ColumnCount += 1;
    tableLayoutPanel1.Controls.Add(button);
  }
}
