我的按钮打印得很笨拙

Question

1. 我有一张表，我在每行的末尾打印一个按钮。我希望这个按钮很小。

2. 尽管使用溢出省略号，但在打印表格时，我的文本不会被截断。我不想要水平滚动条。

3. 我的表格标题栏，当我向下滚动时，最上面一行总是隐藏。



非常感谢任何帮助。这是我的 CSS 脚本https://jsfiddle.net/v6sahfyc/1/

编辑：在这里添加php代码：

// <?php   
    // echo "<div id='awesometable'>"; 
// ?>

<!-- <CAPTION>RESERVATION TABLE</CAPTION> -->
<?php   

    echo "<br><br><p style=\"font-family:verdana; font-size:100%; margin-left: 5em;\"><i><strong>Reservation Table.</strong></i></p>";
    echo "<table id='reservation' class='inlineTable'>";  //style='border: solid 1px black;'
    //echo "<thead>";
    echo "<tr>";
    echo "<th class=\"row-1 uid\">UserId</th>";
    echo "<th class=\"row-2 rname\">Resource <br> Name</th>";
    echo "<th class=\"row-3 rtype\">Resource <br> Type</th>";
    echo "<th class=\"row-4 rloc\">Resource <br> Location</th>";
    echo "<th class=\"row-5 treq\">Time <br> Required </th>";
    echo "<th class=\"row-6 REM\">Delete? </th>";
    echo "</tr>";
    //echo "</thead>\n";            
    //echo "<col = width: 3em />";
?>

              echo "<tr><td>{$row['user_ID']}</td><td>{$row['ResourceName']}</td><td>{$row['ResourceType']}</td><td>{$row['ResourceLocation']}</td><td>{$row['ReservationTime']}</td>";
              $active = $_SESSION['usr'] == $row['user_ID'];
