我的表格当前不显示来自rest api（itunes）的数据，也无法分页。在控制台中，我得到：
<table result="[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]" id="my-table" aria-busy="false" aria-colcount="2" class="table b-table table-sm"><!----><!----><thead role="rowgroup" class=""><!----><tr role="row"><th role="columnheader" scope="col" aria-colindex="1" class="">Artist</th><th role="columnheader" scope="col" aria-colindex="2" class="">Song title</th></tr></thead><!----><tbody role="rowgroup" class=""><!----><!----><!----></tbody></table>
我的组件代码是：
<template>

任何帮助都是好的，因为我不知道这可能发生在哪里，我是Vue的新手，我认为我在表中调用了错误的变量或类似的东西。

将result="..."更改为:result="..."。您需要绑定值（:是v-bind:的快捷方式）。
