JQuery Datatables row height

Question

I have a page where people can enter in first/last name, phone, email, and ethnicity click add and it adds an entry into the datatables. The problem is after clicking add the table shows up like this:

How do I adjust the height of each row so that it shows up properly. This is my html code for the table:

<div id="table">
    <form id="add_nrow" title="Add">
        <br/>
        <label for="name">First Name</label><input type="text" name="fname" id="fname" class="required" rel="0" />
        <br />
        <label for="name">Last Name</label><input type="text" name="lname" id="lname" rel="1" />
        <br />
        <label for="name">Phone</label><input type="text" name="phone" id="phone" rel="3" />
        <br />
        <label for="name">Email</label><input type="text" name="email" id="email" rel="4" />
        <br />
        <label for="name">Ethnicity</label><input type="text" name="ethnicity" id="ethnicity" rel="5" />
        <br />   
        <input type="button" value="Add" id="addbtn" /><br/><br/>  
    </form>

    <table id="reg_more" border="1">
        <thead>
            <tr>
                <th>First Name</th>
                <th>Last Name</th>
                <th>Phone</th>
                <th>Email</th>
                <th>Ethnicity</th>
            </tr>
        </thead>
    </table>
</div>

Here is my jquery code

$("#addbtn").click(addrow);
$('#reg_more').dataTable({
                "bLengthChange": false,
                "bInfo": false,
                "bPaginate": false,
                "bStateSave": true,
                "rowHeight": 'auto',
                "bFilter": true,
                "bSort": false,
                "bAutoWidth": false
            });


function addrow() {
    $('#reg_more').dataTable().fnAddData( [
        $('#fname').val(),
        $('#lname').val(),
        $('#phone').val(),
        $('#email').val(),
        $('#ethnicity').val()] );
    }

I have two questions really:

1. How do I adjust the height properly so the user can see the data?
2. If the enter in the information of 20 people, how do I take all that data so I can enter it into a mysql database?

Answer 1

As you can see in this fiddle your code is correct and should work as expected.

In any case to set a row height, simply use css

 tr { height: 50px } 

i think there is no need for it to be more complex.

Regarding the question on how to insert the data into a db, there are tons of examples on google.
