How to turn the look of a self-written web panel into something more pleasant without extra work?

Question

PHP

Hello. There is a custom web panel. It is designed very simply, the data is inserted into the plate.
The board looks like this

echo '
        <style type="text/css">
        /* <![CDATA[ */
        table, td
        {
            border-color: #600;
                border-style: solid;
        }
        table
        {
            border-width: 0 0 1px 1px;
            border-spacing: 0;
            border-collapse: collapse;
        }
        td
        {
        margin: 0;
        padding: 4px;
        border-width: 1px 1px 0 0;
        background-color: #FFC;
        }
        /* ]]> */
        </style>';

        echo "<table border=1>";
        echo "<tr align='center' class='blue'>";
        echo"<td>Номер ";
        echo"<td>CallerID ";
        echo"<td>IP адрес ";
        echo"<td>NAT ";
        echo"<td>Порт ";
        echo"<td>Пароль ";
//      echo"<td>Status ";
        echo"<td>Registration expiration";
        echo"<td>Межгород";
        echo"<td>Канал";
        echo"<td>Rozetka";

It looked even at the moment of writing 10 years ago, everything is bad, but I'm completely in this oak-oak. How can I fix all this for a more adequate look, so that I don’t have to rewrite all the php there.

Thank you.

Without labor costs - for freelance.
With labor costs - in Google, to read about CSS.
