bootstrapTable标题列出现两次

Question

以下是发生的事情

我无法弄清楚为什么列中的标题会出现两次。我在其他页面上有相同的代码，但它没有这样做。

JQUERY

var $table = $('#table-javascript').bootstrapTable({
    method: 'get',
    url: 'bootstrap_database_email_history.php',
    height: 300,
    cache: false,
    striped: true,
    pagination: true,
    search: false,
    pageSize: 20,
    pageList: [20, 40, 60, 100, 200],
    minimumCountColumns: 2,
    clickToSelect: true,
    columns: [{
        field: 'date',
        title: 'Date',
        align: 'left',
        width: '100'
    },{
        field: 'email', 
        title: 'Email',
        align: 'left',
        width: '20'
    },{
        field: 'sent',
        title: 'Sent',
        align: 'center',
        width: '20'
    },{
        field: 'notsent',
        title: 'Not Sent',
        align: 'center',
        width: '20'
    }]
});

HTML

<table id="table-javascript"></table>

bootstrap_database_email_history.php

<?
include('../includes/connect.php');
$sql = "SELECT * FROM table WHERE this = '$this' ORDER BY ID DESC";
$result = mysql_query($sql);
$records = mysql_num_rows($result);
if ($records == 0) {
    $data['posts'][$i] = $response[$i];
}
$i = 0;
while ($row = mysql_fetch_array($result)) {
    $response[$i]['date'] = $row['date'];
    $response[$i]['email'] = $row['email'];
    $response[$i]['sent'] = $row['sent'];
    $response[$i]['notsent'] = $row['notsent'];
    $data['posts'][$i] = $response[$i];
    $i = $i+1;
    unset($slot);
}
echo json_encode($data['posts']);
?>

JSON响应

[{
    "date":"04\/30\/15",
    "email":"user@user.com",
    "sent":"<\/i>",
    "notsent":""
},{
    "date":"04\/30\/15",
    "email":"user@leader.com",
    "sent":"<\/i>",
    "notsent":""
},{
    "date":"04\/30\/15",
    "email":"user@admin.com",
    "sent":"<\/i>",
    "notsent":""
}]

对我来说，看起来你还没有附上css文件，我可能错了，但这个例子很有效：Demo

public class test {

public static void main(String[] args) {
    JFrame theDog = new JFrame();
    JButton theButton = new JButton("hello");
    //theDog.setSize(200, 200);
    JDialog thadialog = new JDialog(theDog,"theTitle", Dialog.ModalityType.APPLICATION_MODAL);
    thadialog.setVisible(true);
    thadialog.setSize(400,400);
    thadialog.pack();


    System.out.println("hello");
}
}
