bootstrap-table 回调函数中异步和同步的问题

[xxbing]

我想做一个表格,列出用户钱包和其在币安智能链上某个币种的余额 钱包地址全部在 data1.json 中,余额需要实时从链上获取

<script src="https://unpkg.com/bootstrap-table@1.19.1/dist/bootstrap-table.min.js"></script>

<table
  id="table"
  data-toggle="table"
  data-height="460"
  data-url="json/data1.json">
  <thead>
    <tr>
      <th data-field="owner" data-formatter="ownerFormatter">Item Name</th>
      <th data-field="balance" data-formatter="priceFormatter">Item Price</th>
    </tr>
  </thead>
</table>

<script>
  function ownerFormatter(value, row) {
    return '<span>'+value+'</span>';
  }

  async function balanceFormatter(value, row) {
    let wallet_address = row['owner'];
    let sss_balance = 0;
    //window.abi_json 在其他地方定义
    let MyContract = new web3.eth.Contract(window.abi_json,'0xC3028FbC1742a16A5D69dE1B334cbce28f5d7EB3');
    //根据 WEB3 文档在线读取某币种余额 ,console.log(sss_balance)是可以正常打印余额的
    sss_balance = await MyContract.methods.balanceOf(wallet_address).call();
    //返回余额
    return sss_balance;
  }
</script>

上面的 balanceFormatter 肯定是有错误的. async 返回的是一个 Promise 对象,但是删除 async 和内部的 await 也不行.求助大神....太菜了我

priceFormatter ？
balanceFormatter ？

@msg7086 DEMO 写错了,全文上下应该全是 balanceFormatter
