Let's say that in each table row you have three select or other input field.
Each row will look like this (simplified example):
<tr><td><input type="text" name="username[]"></td><td><select name="usertype[]"></td><td><input type="text" name="nickname[]"></td></tr>
The form field name ends with [] as you can see. This is to post all the values as an array and not overwrite them.
When you will post the form you will get that:
$username = $_POST['username'];
$usertype = $_POST['usertype'];
$nickname = $_POST['nickname'];
is an array (and the same for all the other inputs.
Next step is easy:
foreach($username as $key=>$value){
$current_username = $username[$key];
$current_usertype = $usertype[$key];
$current_nickname = $nickname[$key];
//now you insert the single row as usual;
}
