vue 表格计算总计
<el-table v-loading="loading" :summary-method="getSummaries" show-summary :data="abcList" border tooltip-effect="darkTable" >
首先需要在table标签中添加
:summary-method="getSummaries" // 调用方法 show-summary //标签属性 methods: { getSummaries(param) { const { columns, data } = param console.log(columns, data, 'columns,data') const sums = [] columns.forEach((column, index) => { // 设置第一列的值为总计 if (index === 0) { sums[index] = '总计' return } sums[3] = this.form.result sums[3] += '元' }) return sums } }
因为Element上计算总计的方法是计算当前页上金额的总和,稍加修改~
sums[index] = '总计' // 把下标为0的列赋值为总计 sums[3] = this.form.result // this.form.result为init初始化时从接口中拿到的总计,赋值到下标为3的列上 sums[3] += '元' // 得到的总计后加上单位元
