vue?element?ui表格相同數(shù)據(jù)合并單元格效果實例
先看效果
前提是你的數(shù)據(jù)是扁平的數(shù)據(jù)因為要根據(jù)上下數(shù)據(jù)是否一樣才合并的 如果是子級數(shù)據(jù)需要改一下數(shù)據(jù)格式了
下面是數(shù)據(jù)的樣式
tableData: [{ id: '1', name: '王小虎', amount1: '165', amount2: '3.2', amount3: 10 }, { id: '1', name: '王小虎', amount1: '162', amount2: '4.43', amount3: 12 }, { id: '1', name: '王we虎', amount1: '621', amount2: '1.9', amount3: 9 }, { id: '2', name: '王we虎', amount1: '621', amount2: '2.2', amount3: 17 }, { id: '3', name: '王小虎', amount1: '621', amount2: '4.1', amount3: 15 }],
合并單元格的重點屬性就是 :summary-method="" 這個是關(guān)鍵
