原理是將原table的指定行,指定列clone一份放在其上
實現代碼如下:

父組件調用實例:
<template> <table-locked :table-rows="tableData" :grid-columns="gridColumns" :thead="thead" :height="height"> </table-locked> </template> import TableLocked from '../../common/TableLocked.vue' export default{ components: {TableLocked}, data () { data.gridColumns = ['brand', 'product_count', 'averagePrice', 'sales', 'huang_sale_per', 'sale_per', 'sales_amount', 'huang_sale_amount_per', 'sales_amount_per', 'score_num', 'scort_good_per'] data.thead = ['品類', '產品種類', '均價', '銷量', '銷量環比', '銷量占比', '銷額(萬元)', '銷額環比', '銷額占比', '評論總數', '好評率'] } }
