iview,用render函数渲染出来的表格的验证问题

Question

1我想验证Table的Input都是数字，如果不是数字，Input表格框边缘变成红色

 <Table border :columns="discountColumns" :data="discountData.rows"></Table>

     discountData: {
                    total: 1, rows: [
                        {
                            randomDiscountRangeMax: '',
                            randomDiscountRangeMin: '',
                            population: ''
                        },
                    ],
                    defaultRows:
                        {
                            randomDiscountRangeMax: '',
                            randomDiscountRangeMin: '',

                        },
                }
