C# TableLayoutPanel使用方法

一、利用TableLayoutPanel类展示表格，以10行5列为例

第1步：在前台创建一个panel，使TableLayoutPanel对象填充其内部。

第2步：创建TableLayoutPanel类，其实例对象名为table

TableLayoutPanel table = new TableLayoutPanel();

第3步：设置列样式，循环显示行

private void Form2_Load(object sender, EventArgs e)
{
    // 默认添加一行数据
    table.Dock = DockStyle.Top;     //顶部填充
    panel1.Controls.Add(table);     
    table.ColumnCount = 5;          //5列
    table.Height = table.RowCount * 40; //table的整体高度，每行40

    table.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, table.Width * 0.2f));    //利用百分比计算，0.2f表示占用本行长度的20%
    table.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, table.Width * 0.2f));
    table.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, table.Width * 0.2f));
    table.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, table.Width * 0.2f));
    table.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, table.Width * 0.2f));

    for (int i = 1; i <= 10; i++)
    { 
        AddRow("苹果"+i.ToString().PadLeft(2,'0'),"橘子" + i.ToString().PadLeft(2, '0'), "香蕉" + i.ToString().PadLeft(2, '0'), "香瓜" + i.ToString().PadLeft(2, '0'), "甘蔗" + i.ToString().PadLeft(2, '0'));
    }
}

第4步：设置每一行样式

private void AddRow(string apple, string orange, string banana, string casaba, string sugarcane)
{
    try
    {
        // 动态添加一行
        table.RowCount++;
        //设置高度,边框线也算高度，所以将40修改大一点
        table.Height = table.RowCount * 44; 
        // 行高
        table.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Absolute, 40));
        // 设置cell样式，增加线条
        table.CellBorderStyle = TableLayoutPanelCellBorderStyle.OutsetPartial;

        int i = table.RowCount - 1;

        Label label1 = new Label();
        label1.Text = apple;
        label1.Width = 200;
        label1.Height = 40;
        label1.Font = new Font("隶书", 13, FontStyle.Bold);
        label1.TextAlign = ContentAlignment.MiddleCenter;
        table.Controls.Add(label1, 0, i);

        Label label2= new Label();
        label2.Text = orange;
        label2.Width = 200;
        label2.Height = 40;
        label2.Font = new Font("隶书", 13, FontStyle.Bold);
        label2.TextAlign = ContentAlignment.MiddleCenter;
        table.Controls.Add(label2, 1, i);

        Label label3 = new Label();
        label3.Text = banana;
        label3.Width = 200;
        label3.Height = 40;
        label3.Font = new Font("隶书", 13, FontStyle.Bold);
        label3.TextAlign = ContentAlignment.MiddleCenter;
        table.Controls.Add(label3, 2, i);

        Label label4 = new Label();
        label4.Text = casaba;
        label4.Width = 200;
        label4.Height = 40;
        label4.Font = new Font("隶书", 13, FontStyle.Bold);
        label4.TextAlign = ContentAlignment.MiddleCenter;
        table.Controls.Add(label4, 3, i);

        Label label5 = new Label();
        label5.Text = sugarcane;
        label5.Width = 200;
        label5.Height = 40;
        label5.Font = new Font("隶书", 13, FontStyle.Bold);
        label5.TextAlign = ContentAlignment.MiddleCenter;
        table.Controls.Add(label5, 4, i); 
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message.PadRight(30, ' '), "提示", MessageBoxButtons.OK, MessageBoxIcon.Error); 
    }
}

查询某行某列数据

private void button1_Click(object sender, EventArgs e)
{
    //查询第4行第4列数据，下标从0开始
    int i = 3;
    int j = 3;
    Label label = (Label)table.Controls[i * 5 + j];
    MessageBox.Show(label.Text); 
}

修改某行某列数据

private void button2_Click(object sender, EventArgs e)
{
    //修改第6行第1列数据，下标从0开始
    int i = 5;
    int j = 0;
    Label label = (Label)table.Controls[i * 5 + j];
    label.Text = "已修改";
    label.ForeColor = Color.Red;
}

 

二、TableLayoutPanel控件属性

1.单元格画线使用CellBorderStyle属性

2.合并单元格，例如一行一列和一行二列合并

首先在一行一列单元格内添加Panel控件，修改器属性ColumnSpan = 2 即可
