一、需求
满足用户自行配置表格,减少对系统代码维护量。
二、效果
表头json:
说明:scope(字段名可另取)为是否对该列开启插槽。有propChildren包含多级表头。
tableHead: [{ key: '1', label: '日期', prop: 'date', width: '100', headerAlign: 'center', align: 'center', scope: false, sortable: true }, { key: '2', label: '姓名', prop: 'name', width: '100', headerAlign: 'center', align: 'center', scope: false, sortable: false }, { key: '3', label: '分析情况', prop: 'analysis', width: '100', headerAlign: 'center', propChildren: [{ key: '31', label: '同比', prop: 'TB', width: '100', headerAlign: 'center', align: 'center', scope: true, sortable: true }, { key: '32', label: '环比', prop: 'HB', width: '100', headerAlign: 'center', align: 'center', scope: true, sortable: true },] }, { key: '4', label: '金额', prop: 'price', width: '100', headerAlign: 'center', align: 'right', scope: false, sortable: true }, { key: '5', label: '地址', prop: 'address', width: '', headerAlign: 'left', align: 'left', scope: false, sortable: false } ],
