                            amount1: '2',
                          }, {
                            date: '2',

                          ],

方法

  getSummaries(param) { // 上面自定义 内容 const { columns, data } = param; const sums = []; columns.forEach((column, index) => { if (index === 0) { sums[index] = '总价'; return; } const values = data.map(item => Number(item[column.property])); console.log(values) if (!values.every(value => isNaN(value))) { sums[index] = values.reduce((prev, curr) => { const value = Number(curr); if (!isNaN(value)) { return prev + curr; } else { return prev; } }, 0); sums[index] += ' 元'; } else { sums[index] = 'N/A';//当不是number数字是返回的内容 } }); console.log(sums); // 先看输出格式，看最终要返回什么数据 return sums; },
