vue 表格计算总计

>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vue table表格合计 ( Element )
