The execute command has special behaviour when placed on
       a <table> element. Instead of executing once, it
       executes every detail row in the table and transfers the commands
       from the header row to each detail row.
    
<table concordion:execute="#username = generateUsername(#fullName)">
    <tr>
        <th concordion:set="#fullName">Full Name</th>
        <th concordion:assertEquals="#username">Username</th>
    </tr>
    <tr>
        <td>Fred Bloggs</td>
        <td>fredbloggs</td>
    </tr>
    <tr>
        <td>John Doe</td>
        <td>johndoe</td>
    </tr>
    <tr>
        <td>Winston Churchill</td>
        <td>winston</td>
    </tr>
</table>
        
            If the method generateUsername() returns the
            full name in lowercase with spaces removed, when we run
            the test we expect:
            2 successes and
            1 failure and
            0 exceptions 
            to be reported.
            The failure will have an expected value of
             "winston"
            and an actual value of
             "winstonchurchill".
