<table name="tiba" class="tiba" width="100%" height="96%">
        <tr>

        </tr>
        <tr>
          <td width="932" height="22">&nbsp;&nbsp;&nbsp;&nbsp;由于Lodop可以指定在纸张的某个区域输出一个或多个内容，故对全页来说没有传统意义上的边距概念。</td>                 
        </tr>
        <tr>
          <td  style="vertical-Alignment: top" width="932" height="22">但对于单个内容来说是有边距概念的，特别当无法确定某内容在每页内的宽度或高度时，用边距就显得方便和好理解。</td>
        </tr>
        <tr>
          <td width="932" height="22">

          设置右边距和下边距的方法有好几个，最简单的办法是用ADD类语句参数的转义关键字,例如下面的语句:

          <td  style="vertical-Alignment: top" width="932" height="22">

          </td>
        </tr>
        <tr>
          <td  style="vertical-Alignment: top" width="932" height="22">
          <b>参数说明：</b>

        <tr>
          <td  style="vertical-Alignment: top" width="932" height="22">
          <font size="3">1:其中前两个参数设置<b><font color="#0000FF">上边距</font></b>和<b><font color="#0000FF">左边距</font></b>分别为5mm和34px(1px=1/96英寸）；</font> 
          </td>
        </tr>
        <tr>
          <td  style="vertical-Alignment: top" width="932" height="29">
          <font size="3">2:关键字<font color="#0000FF">RightMargin</font>和<font color="#0000FF">BottomMargin</font>使后俩参数不再直接设置宽度和高度，</font><font size="3">而是设置<b><font color="#0000FF">右边距</font></b>和<b><font color="#0000FF">下边距</font></b></font>(变相控制宽高)；&nbsp;

          <td  style="vertical-Alignment: top" width="932" height="22">
          3:计量单位可混合使用，可以是百分比，但注意控件内部是以px为基本单位，换算会有细微误差；

          <td  style="vertical-Alignment: top" width="932" height="22">&nbsp;&nbsp;&nbsp;  
            用以上语句<a href="javascript:myPreview1()">打印预览1</a>本页看看，观察边距；如果仅<a href="javascript:myPreview2()">打印预览2</a>如下表格会感觉更明显。</td>

          <td  style="vertical-Alignment: top" width="932" height="22">


          <font size="2">(注意超文本中body元素的margin也要设为0才能让表格线贴近以上设置的边缘)</font>
