DataTables Padding Top 0如何设置

Question

我有3个DataTables表。他们的ID是＃example2，＃example2，＃example3。

我有填充前0的问题，我想设置填充前0，但在尝试了很多个小时后我筋疲力尽。

<table>
    <tr>
        <td width="850px">
            <div></div>
            <div>
                <table id="example2" class="display" cellspacing="0">
                    <thead>
