iview 使用:span-method="handleSpan"合并行/列，未执行handleSpan方法，求大神指导已解决 少引用了iviewUI<Table :columns="columns14" :data="data5" :span-method="handleSpan"></Table>columns14: [ { title: 'Date', key: 'date' }, { title: 'Name', key: 'name' }, { title: 'Age', key: 'age' }, { title: 'Address', key: 'address' }],data5: [ { name: 'John Brown', age: 18, address: 'New York No. 1 Lake Park', date: '2016-10-03' }, { name: 'Jim Green', age: 24, address: 'London No. 1 Lake Park', date: '2016-10-01' }, { name: 'Joe Black', age: 30, address: 'Sydney No. 1 Lake Park', date: '2016-10-02' }, { name: 'Jon Snow', age: 26, address: 'Ottawa No. 2 Lake Park', date: '2016-10-04' }]handleSpan ({ row, column, rowIndex, columnIndex }) { console.log(9999999999999) if (rowIndex === 2 && columnIndex === 0) { return { rowspan: 2, colspan: 1 }; } else if (rowIndex === 3 && columnIndex === 0) { return { rowspan: 0, colspan: 0 }; }},直接将官方的数据扒过来本地还是不执行，9999都打印不出。求大神指示版本号如下"vue": "^2.5.2","iview": "^3.5.4",
