<table cellpadding="0" cellspacing="0" border="1" style="margin:auto; width:96%;" id="LearnInfoItem"> 
<tr > 
<td colspan="8" bgcolor="#96E0E2" style="height:30px;" ><h3 style="text-align:center; margin:0;">主要學習簡歷</h3></td> 
</tr> 
<tr id="tr1"> 
<td class="tdStyle2">起訖時間 </td> 

<td class="tdStyle2">畢業院校</td> 

<td class="tdStyle2">所學專業</td> 

<td class="tdStyle2">學制</td> 

<td class="tdStyle2">學位</td> 

<td class="tdStyle2">學習方式</td> 

<td class="tdStyle2">文化程度</td> 

<td class="tdStyle2"> 
<input type="button" name="LearnAdd" value="添加" onclick="LearnAddSignRow()" /> 
<input name='LearnTRLastIndex' type='hidden' id='LearnTRLastIndex' value="1" /> 
</td>
