存档/表不像它应该的那样

Question

https://s27.postimg.org/niua66jqr/archive.jpg

我有我的表，因为它在右图中，但我不得不在archive.php文件中添加一些代码。我没有修改任何存档表代码，只是添加了页眉和页脚。现在，它看起来像左边的图像。我可以更改style.css文件中的某些内容（例如display:？）或修改某些原始存档代码吗？

<div class="archive-container">

    <h2><?php the_title(); ?></h2>

        <script type="text/javascript">
            var domainroot="sitetitle.com"
            function Gsitesearch(curobj){
                curobj.q.value="site:"+domainroot+" "+curobj.qfront.value
                }

        </script>


        <form action="http://www.google.com/search" method="get" onSubmit="Gsitesearch(this)">

            <p class="search">Search:<br />
            <input name="q" type="hidden" class="texta" />
            <input name="qfront" type="text" style="width: 186px; text-size: 12px; height: 14px;" /> </p>

        </form>


        <table id=arc>
            <?php
