すべてのコードを読んだわけではありませんが、次の方法で出力をバッファリングできます。

あなたはできません

            setcookie("jobID", $jobID);

データが既にブラウザにプッシュされた後。

mysql_fetch ループ内で Cookie を設定しようとしています。

テーブルをエコーし​​ないでください。

<?php
    $jobID = 0;
    $rows = 0;
    $errors = 0;
    $DBConnect = @mysql_connect("localhost", "root");

    if($DBConnect === FALSE)
    {
        $str = "<p>Unable to connect to the database server. " .
        "Error code " . mysql_errno() . ": " .
        mysql_error() . "</p>\n";
        $errors++;
    }
    else
    {
        $DBName = "nokeekwe";
        $result = @mysql_select_db($DBName, $DBConnect);

        if($result === FALSE)
        {
            $str = "<p>Unable to select the database. " .
            "Error code " . mysql_errno($DBConnect) . ": " .
            mysql_error($DBConnect) . "</p>\n";
            $errors++;
        }
    }
    if($DBConnect !== FALSE)
    {
        $jobID = 0;
        $errors = 0;
        $title = "";

        $req = "";
        $employer = "";
        $phone = "";
        $fax = "";
        $email = "";
        $address = "";
        $TableName = "tbljobs";
        $SQLstring = "SELECT * FROM tbljobs";
        $QueryResult = @mysql_query($SQLstring, $DBConnect);

        while(($Row = mysql_fetch_row($QueryResult)) !== FALSE)
        {
            $jobID = $Row[0];
            setcookie("jobID", $jobID);
            $str .= "<table>\n";
            $str .= "<tr><td>Job ID #: $Row[0]</td></tr>\n";
            $str .= "<tr><td>Job Title: $Row[1]</td></tr>\n";
            $str .= "<tr><td>Job Description: $Row[2]</td></tr>\n";
            $str .= "<tr><td>Job Requirements: $Row[3]</td></tr>\n";
            $str .="<tr><td>Employer: $Row[4]</td></tr>\n";
            $str .="<tr><td>Phone: <br /> $Row[5]</td></tr>\n";
            $str .="<tr><td>Fax: <br /> $Row[6]</td></tr>\n";
            $str .="<tr><td>Email: <br /> $Row[7]</td></tr>\n";
            $str .="<tr><td>Address: <br /> $Row[8]</td></tr>\n";
            $str .="<form action='editJobs.php' method='request'><button name='func' value='edit'>Edit</button><button name='func' value='delete'>Delete</button></form></tr>\n";
            $str .="</table>\n";;

        }   
    }
    $rows =  mysql_num_rows($QueryResult);
    if($rows == 0)
    {
        $str .="no jobs to show\n";
    }
    mysql_close($DBConnect);
?>

そのビットをページの一番上に移動します。

後、

<div class="wideBox">

追加：

<?=$str;?>

これにより、Cookie を設定する前に情報がブラウザに送信されるのを防ぐことができます。

また、設定された Cookie は、MySQL ループ内では明るいアイデアではありません。複数の行を返す場合は、最後に返された行の値を設定するだけです。
