JSON数据无法在HTML表格显示的技术求助

我尝试将contas.json文件中的数据输出到HTML表格中，已实现按字段类型划分的搜索过滤功能（手动添加测试数据时过滤可正常工作），但通过fetch加载JSON数据后，数据无法在创建的HTML页面中可视化展示，不清楚问题出在哪里，恳请提供帮助。相关代码如下：

HTML代码（仅数据展示部分） #

<head>
    <title>Page Test</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="bootstrap.min.css">
    <script src="jquery-3.6.3.slim.min.js"></script>
    <script src="tablesearch.js"></script>
    <script src="script.js"></script>
</head>

<div class="row">
    <div class="col-sm-12">
        <input type="text" class="myInput" onkeyup="searchTable(this.value, 'list')"
            placeholder="Buscar en la tabla completa..." title="Search">
        <input type="text" class="myInput" onkeyup="searchTable(this.value, 'list', 0)"
            placeholder="Seleccionar por país..." title="Search">
        <input type="text" class="myInput" onkeyup="searchTable(this.value, 'list', 1)"
            placeholder="Seleccionar por ciudad..." title="Search">
        <input type="text" class="myInput" onkeyup="searchTable(this.value, 'list', 2)"
            placeholder="Seleccionar por cuenta..." title="Search">

        <table id="list" class="table table-striped">
            <thead>
                <tr>
                    <th>País</th>
                    <th>Ciudad</th>
                    <th>Cuenta</th>
                    <th>URL</th>
                </tr>
            </thead>
            <tbody id="stats-output">

            </tbody>
        </table>
    </div>
</div>

JavaScript代码（script.js） #

fetch("contas.json")
    .then(function (response) {
        return response.json();
    })
    .then(function (contas) {
        let placeholder = document.querySelector("#stats-output");
        let out = "";
        for (let conta of contas) {
            out += `
            <tr>
                <td>${conta.Country_Code}</td>
                <td>${conta.Account_City}</td>
                <td>${conta.Account_Name}</td>
                <td> <a href="${conta.Account_Link}"> Clic aquí </a></td>
            </tr>
        `;
        }

        placeholder.innerHTML = out;
    });

表格搜索JavaScript代码 #

注：仅作信息参考，手动添加如下测试数据时过滤功能可正常工作：

<tr>
   <td>AR</td>
   <td>Ciudad</td>
   <td>Cuenta</td>
   <td>Encuesta Link</td>
</tr>

function searchTable(input, tableId, searchColumn = -1, searchColumn2 = -1, searchColumn3 = -1) 
{
    var filter = input.toUpperCase();
    var table = document.getElementById(tableId);
    var rowText, rowText2, rowText3;    //temporary var
    
    for (var i = 0, row; row = table.rows[i]; i++) {
        //iterate through rows
        if (searchColumn == -1) //by default, search all columns
        {
            if (i != 0) {   //don't perform search on the first row header
                rowText = row.innerHTML;    //get text for the whole row
                if (rowText.toUpperCase().indexOf(filter) > -1) {   //if upper case matches any part of filter
                    row.style.display = "";
                }
                else {

                }
            }
