01.DataGridView 多個欄位偽裝成單一欄位列表 [單純屬性設定]
//標籤列設定&隱藏

//設定ScrollBars

02.DataGridView 透過自訂函數細部設定

//dataGridView1.ReadOnly = true;//唯讀 不可更改

for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
dataGridView1.Columns[i].ReadOnly = true;//單一欄位禁止編輯
dataGridView1.Columns[i].DefaultCellStyle.NullValue = null;//允許單一圖片放空，不顯示X圖
}
//設置所有行背景色
dataGridView1.RowsDefaultCellStyle.BackColor = Color.Pink;//Color.White;
//設置奇數行背景色（下標從零開始）
dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.YellowGreen;
//選擇顏色指定
dataGridView1.RowsDefaultCellStyle.SelectionBackColor = Color.Red;
//將行高調整到適合螢幕上當前顯示的行中所有單元格（包括標頭單元格）的內容。
dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.DisplayedCells;
//允許換行屬性設定
dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
dataGridView1.AllowUserToAddRows = false;//刪除空白列
dataGridView1.SelectionMode = System.Windows.Forms.DataGridViewSelectionMode.FullRowSelect;//整列選取
//--
do
{
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
