请教一下如何实现表单点击新增一行,还有表单里如何实现删格代码?

const onAddArrayItem = () => {
    baTable.form.items!.array.push({
        a: 0,
        b: 0,
        c: 1,
        d: 0,
        e: '',
        f: 0,
        g: '',
    })
}

const onDelArrayItem = (idx: number) => {
    baTable.form.items!.array.splice(idx, 1)
}
