項目中采用 vue + elementui 開發,表格要求動態合並。
前一篇文章《element-ui table動態列合並--支持多個列 開箱即用》(網址:https://www.cnblogs.com/smile-fanyin/p/13566337.html)的內容相當於靜態展示,定義好方法,拿來數據展示就行。
而項目中的表格要求動態操作。所以根據前一篇文章的基礎,改進而來。
需求:
1、以事項列為主操作,可以向下合並,可以無限向下合並;
2、事項列合並的同時,操作、序號、歷史情況、本次調整原因、狀態、審批流程列跟着變化,授權節點列不變化;
3、事項描述列比較特殊,可以自己單獨合並,也可以不合並,但是前提是必須是在事項合並的行數范圍內。因為事項描述 歸屬於 事項,所以事項描述列合並的時候,不能跨不同的事項行。
4、關於操作:首列的操作可以增加一行,也可以刪除一行。事項描述列可以添加,也可以刪除。
代碼如下:
