DataGridView

目标：实现如下类似效果

核心代码：

            dataGridView1.Rows[row].Cells[col].Style.Padding =
                new Padding(dataGridView1.Rows[row].Cells[col].OwningColumn.Width, 0, 0, 0);
            dataGridView1.Rows[row].Cells[col].Style.BackColor = Color.Gray;

代码

namespace TestDGV
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void AddRow_Click(object sender, EventArgs e)
        {
            this.dataGridView1.Rows.Add();
        }

        private void AddColumn_Click(object sender, EventArgs e)
        {
            string colInfo = this.ColumnName.Text;
            if(string.IsNullOrEmpty(colInfo))
            {
                MessageBox.Show("Column Info Empty.");
                return;
            }
            if(dataGridView1.Columns.Contains(colInfo))
            {
                MessageBox.Show("Column Name Exist.");
                return;
            }
            var c = new DataGridViewTextBoxColumn();
            c.HeaderText = colInfo;
            c.Name = colInfo;
            dataGridView1.Columns.Add(c);
        }

        private void GreyCell_Click(object sender, EventArgs e)
        {
            int row;
            if(!Int32.TryParse(this.RowIndex.Text,out row))

                return;

            if (row >= this.dataGridView1.Rows.Count)
                return;

            if (col >= this.dataGridView1.Columns.Count)
                return;
            dataGridView1.Rows[row].Cells[col].Style.Padding =
                new Padding(dataGridView1.Rows[row].Cells[col].OwningColumn.Width, 0, 0, 0);
