我表中相同的标题显示不同

Question

我正在运行查询并将结果加载到表中以供显示。一些查询正在提取相同的数据，但它在表格中的显示方式不同。例如，联系人在3个表中的1个上显示不同。这些表格显示在iframes中，来自不同的网页。

table, td, th {
    border: 1px solid green;
    text-align: center;
    padding: 1px;
}

th {
    background-color: green;
    color: white;
}

table { 
    margin-left: auto;
    margin-right: auto;
}

iframe {
    display: block; /*new*/
    margin: auto;
    border: none; /*revised*/
    width: 800px;
    height: 200px;
}

div.center p {
    text-align: center;
} /*new*/ 

<div class="center">
    <p>
        <button onclick="myFunction1()">Current Projects</button>
        <button onclick="myFunction2()">Completed Projects</button>
        <button onclick="myFunction3()">Projects in Final Review</button>
    </p>
</div>

<script>
    var iframeExists = false;

    function myFunction1() {
        var x
        if (!iframeExists) {
            x = document.createElement("IFRAME");
            iframeExists = true;
        } else {
            x = document.getElementsByTagName("IFRAME")[0];
        }
        x.setAttribute("src", "http://www.oldgamer60.com/Project/CurrentProjects.php");
        document.body.appendChild(x);
    }

    function myFunction2() {
        var x;
        if (!iframeExists) {
            x = document.createElement("IFRAME");
            iframeExists = true;
        } else {
            x = document.getElementsByTagName("IFRAME")[0];
        }
        x.setAttribute("src", "http://www.oldgamer60.com/Project/CompletedProjects.php");
        document.body.appendChild(x);
    }

    function myFunction3() {
        var x;
        if (!iframeExists) {
            x = document.createElement("IFRAME");
            iframeExists = true;
        } else {
            x = document.getElementsByTagName("IFRAME")[0];
        }
        x.setAttribute("src", "http://www.oldgamer60.com/Project/ProjectsInFinalReview.php");
        document.body.appendChild(x);
    }
</script>
