Transform 数据集数据转换

基本用法

<script setup>
    import { ref } from 'vue'

    const data = [
        ['Product', 'Sales', 'Price', 'Year'],
        ['Cake', 123, 32, 2011],
        ['Cereal', 231, 14, 2011],
        ['Tofu', 235, 5, 2011],
        ['Dumpling', 341, 25, 2011],
        ['Biscuit', 122, 29, 2011],
        ['Cake', 143, 30, 2012],
        ['Cereal', 201, 19, 2012],
        ['Tofu', 255, 7, 2012],
        ['Dumpling', 241, 27, 2012],
        ['Biscuit', 102, 34, 2012],
        ['Cake', 153, 28, 2013],
        ['Cereal', 181, 21, 2013],
        ['Tofu', 395, 4, 2013],
        ['Dumpling', 281, 31, 2013],
        ['Biscuit', 92, 39, 2013],
        ['Cake', 223, 29, 2014],
        ['Cereal', 211, 17, 2014],
        ['Tofu', 345, 3, 2014],
        ['Dumpling', 211, 35, 2014],
        ['Biscuit', 72, 24, 2014]
    ]
