I need a script to make input field fill the rest of the screen relative to screen size

Question

This below code is what I have donr. I need the third input field "description" to spread into width, according to size of the screen, but I don't know how to get there:

echo("<table cellspacing=\"0\" cellpadding=\"4\" width=\"100%\">\n");
echo("<tr class=\"header\" ALIGN=LEFT>\n");
echo("<th>NUmber</th>\n");
echo("<th>Descrtiption</th>\n");
echo("</tr>\n");


echo("<form method=\"post\">\n");
echo("<tr class=\"class1\">");
echo("<td><input type=\"text\" maxlength=\"10\" size=\"6\" name=\"number\" tabindex=\"1\"></td>\n");
echo("<td><input type=\"text\" size=\"70\" name=\"description\" tabindex=\"4\"></td>\n"); 
echo("</tr>");
echo("</form>\n");

This is how i learned to do it, but I don't know how to make selector for the second column width :/

function init() {
    document.getElementById('description').style.width='100%';
}

window.onload = init;

Thank you very much!

Use <td width="100%"><input type="text" style="width:100%" name="description" tabindex="4"></td>.
