here is example code
<table class="tab-form">
<tbody id="ztable">
<tr class="scnd" id="row1">
<td class="td-num" style="width: 25px;">1</td>
<td class="td-pin">
<input type="text" class="inp pin" maxlength="4" /> - <input type="text" class="inp pin" maxlength="4" /> - <input type="text" class="inp pin" maxlength="4" /> - <input type="text" class="inp pin last_pin" maxlength="4" />
</td>
<td class="td-hint">
<img src="/images/ico-quest.gif" width="18" height="18" alt="" class="show_help_btn cursor_p" />
</td>
<td class="td-pasw" style="width: 173px;">
<img src="/images/but-pasw_en.gif" width="152" height="20" alt="" class="show_pass_btn cursor_p" />
<div class="pass_box"><span id="pass_first"></span><input type="password" class="inp_pass" /></div>
</td>
<td class="td-online">
