在上面属性学习的基础上 通过编码来创建我们需要的TableLayoutPanel的相关布局

下面想要实现的效果为：

点击一次按钮 TableLayoutPanel将新增两行

此两行的相关控件布局如下

button1    button2

               button3

再点击一次按钮 将又会新增两行

button4   button5

              button6

其中我们也将对按钮加入相关事件

点击button1 得到自身的Name值

点击button2 得到其对应的button1的Text值 (button5对应于button4)

点击button3 将删除自身及其对应的button1 和 button2(点击button6将删除button6 button5 button4)

相关示例代码如下

public partial class tableLayoutPanelForm : Form
{
    public tableLayoutPanelForm()
    {
        InitializeComponent();
    }


    private void tableLayoutPanelForm_Load(object sender, EventArgs e)

        this.panel1.BorderStyle = BorderStyle.FixedSingle;

        TableLayoutPanel tabPanel = new TableLayoutPanel();
        tabPanel.ColumnCount = 2;
        
        this.panel1.Controls.Add(tabPanel);
    }


    int iClickedTimes = 0;
    //每点击一次 新增如下结构
    //btn1    btn2
    //        btn3
    //btn1跨两行
    private void button1_Click(object sender, EventArgs e)
    {           
        TableLayoutPanel tabPanel = (TableLayoutPanel)(this.panel1.Controls[0]);
        tabPanel.RowCount = (iClickedTimes + 1) * 2;  //再增两行          

        //增加button1
        Button btn1 = new Button();
        btn1.Name = "button" + (iClickedTimes * 3 + 1).ToString();

        btn1.Click += new EventHandler(btn1Click);//事件
        tabPanel.Controls.Add(btn1, 0, iClickedTimes*2);
        tabPanel.SetRowSpan(btn1, 2);//跨两行

        //增加button2
        Button btn2 = new Button();
        btn2.Name = "button" + (iClickedTimes * 3 + 2).ToString();
        btn2.Text = "buttonText" + (iClickedTimes * 3 + 2).ToString();
        btn2.Click += new EventHandler(btn2Click);
        tabPanel.Controls.Add(btn2, 1, iClickedTimes * 2);

        //增加button3
        Button btn3 = new Button();
        btn3.Name = "button" + (iClickedTimes * 3 + 3).ToString();
        btn3.Text = "buttonText" + (iClickedTimes * 3 + 3).ToString();
        btn3.Click += new EventHandler(btn3Click);
        tabPanel.Controls.Add(btn3, 1, iClickedTimes * 2 + 1);

        tabPanel.Size=new Size(200, (iClickedTimes + 1) * 2 * 50);

        iClickedTimes++;
    }
    //自身的Name
    private void btn1Click(object sender, EventArgs e)
    {
        Button btn1 = (Button)sender;
        MessageBox.Show(btn1.Name);
    }
    //通过命名规则 得到其对应btn1的Text
    private void btn2Click(object sender, EventArgs e)
    {
        Button btn2 = (Button)sender;
        string btn2ID = btn2.Name.Substring(6);//去掉Name中的button
        //其对应btn1的Name为
        string btn1Name = "button" + Convert.ToString((Convert.ToInt32(btn2ID) - 1));
        //
        TableLayoutPanel tabPanel = (TableLayoutPanel)(this.panel1.Controls[0]);
        string btn1Text = ((Button)(tabPanel.Controls[btn1Name])).Text;
        MessageBox.Show(btn1Text);
    }

    //删除其所在行列 btn1,btn2,btn3
    private void btn3Click(object sender, EventArgs e)
    {
        Button btn3 = (Button)sender;
        TableLayoutPanel tabPanel = (TableLayoutPanel)(this.panel1.Controls[0]);

        //一种删除方法 得到其对应btn1 btn2的Name
        string btn3ID = btn3.Name.Substring(6);
        string btn1Name = "button" + Convert.ToString((Convert.ToInt32(btn3ID) - 2));
        string btn2Name = "button" + Convert.ToString((Convert.ToInt32(btn3ID) - 1));
        tabPanel.Controls.Remove(btn3);
        tabPanel.Controls.Remove(tabPanel.Controls[btn2Name]);
        tabPanel.Controls.Remove(tabPanel.Controls[btn1Name]);
    }
