两张桌子并排并停止自动中心

Question

我创建了两个表并完美地编写了代码，但是当得到足够长的时候，有些正确的表会将自己置于中心位置。我该如何解决这个问题？

这是我的代码：

#schoolmates_tableMain {
width: 30%;
border: 1px;
min-width: 30%;
position: relative;
opacity: 0.99;
background-color: rgba(100, 100, 100, 0);
float: left;
}


#schoolmates_table { 
width: 59%;
border: 1px;
min-width: 59%;
position: relative;
margin: auto; 
padding-top: 10px;  
background: transparent;
}

更新

我也尝试将float:right;放在右表上，结果如下：

正确的表格“退出了背景”，如果完全被击落，你可以看到滚动条我甚至看不到“添加好友”链接。如何使正确的表格看起来像第一张图片并保持正确？

HTML

<div id = "green_center">
        <br/><br/>

        <table id = "schoolmates_tableMain" cellspacing = 30>
            <tr id = "transparent">
                <td width = "30%">

                    <br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>

                </td>

            </tr>
        </table>

            }


            }
        ?>

        <br/><br/><br/><br/><br/><br/>
        </div>

这是我的green_center代码：

#green_center {

margin-left: auto;
margin-right: auto;
text-align: center;
background-color: #D8F0DA;
width: 100%;
height: auto;
min-height: 100%;
position: relative;

background-image: url(../img/wallpaper.jpg); 
background-position:center center;
background-repeat:no-repeat;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-attachment: fixed;

overflow: auto;

}
