最近做個項目中需要打印DataGridView中數據，因爲產品質量存在三六九等，因此如果正常打印的話，會出現一條信息很長，其他信息很短情況，爲讓打印更美觀，節約成本，需要將某幾行變爲橫向的。這次我介紹一下關鍵代碼部分。
/// <summary>
/// 打印單元格（行轉列）
/// </summary>
/// <param name="dataGridView">DataGridView表</param>
/// <param name="limtRow">每一頁控制行數</param>
/// <param name="n">頁數</param>
/// <param name="groupNumber">多個待轉列爲一組</param>
/// <param name="eachGroupNo">每一組多少列</param>
/// <param name="AluxityStartCol">其他列的起始列</param>
/// <param name="AluxityEndCol">其他列的終止列</param>

轉行後的效果如下：
說明以下：首列是0，共6組（編號，LOT色，數量），每組3列，其他列的起始列： 3，其他列的終止列：4；
希望對你有幫助！
