Drupal主题使用tpl文件

How to present the fields of my form in a way that every row has 2 fields in Drupal 7? I want to do it using tpl.php files instead of directly through CSS. Could anyone please help?

Below I have provided the basic code of my form. Please check it out and tell if anything else is required.

  $items['example/mfrp']=array(
        'title'=>'Example Form',
        'dsecription'=>'My first Real Time Project',
        'page callback'=>'drupal_get_form',
        'page arguments'=>array('mfrp_form'),
        'access callback'=>TRUE,
    );



 function mfrp_form($form,&$form_state){
    $form['name']=array(
        '#title'=>t("University Name"),
        '#type'=>'textfield',
        //'#value'=> t("Enter University name"),
        '#placeholder' => t('Enter your name here'),
        '#required'=> TRUE,


    );
    $form['address']=array(
        '#title'=>t("Unversity Address"),
        '#type'=> 'textfield',
        //'#value'=> t("Enter University address"),
        '#placeholder' => t('Enter your address here'),
        '#required'=> TRUE,


    );
     $form['#attributes']['enctype'] = 'multipart/form-data'; // If this is not
    // Here, upload will fail on submit
    // $form['#attributes']['placeholder'] = "Enter your input here";
   $form['logo'] = array(
        '#title'=> t('University Logo'),
        '#type'         => 'file',
        '#value'=>t("Enter University logo"),
        //'#required'=> TRUE,
        '#description'  => t('Images must be one of jpg, gif or png formats.'),

    );


$form['specialisation'] = array(
    '#type' => 'radios',
    '#title' => t('Choose your specialisation'),
    '#description' => t('Select a University Specialisation'),
    '#options' => array(
    t('Arts'),
    t('Commerce'),
    t('Science')),
    '#default_value' => isset($form_state['values']['specialisation']) ? $form_state['values']['specialisation'] : '',
    '#required'=> TRUE,
    );

    $form['website']=array(
        '#title'=>t("Univerity Website"),
        '#type'=>'textfield',
        //'#value'=>t("Enter University website"),
        '#placeholder' => t('Enter your website here'),
        '#required'=>TRUE,
    );

    $form['newsletter']=array(
        '#type'=>'checkbox',
        '#title'=>t("Do you want to receive newsletters in your email"),
        '#required'=>TRUE,
    );

    $form['submit']=array(
        '#type'=>'submit',
        '#value'=>'Submit',
        '#required'=>TRUE,
        '#submit' => array('mfrp_form_submit'),
        );

    return $form;    
}

Thanks in advance.
