CSS:

body{margin:0px;padding:0px;-moz-user-select:none;cursor:default;}

.splitx{overflow:hidden;position:absolute;height:3px;cursor:row-resize;background:red !important;filter:Alpha(opacity=10);-moz-opacity:0.1;opacity: 0.1; }
.splity{overflow:hidden;position:absolute;width:3px;cursor:col-resize;background:red !important;filter:Alpha(opacity=10);-moz-opacity:0.1;opacity: 0.1;}
#tabletitle{font-weight:bold;font-size:18px;height:30px;width:800px;margin:0 auto;text-align:center;font-family:宋体;line-height:30px;}
#tabletitle input{width:100%;border:0px;height:28px;line-height:30px;text-align:center;font-weight:bold;font-size:18px;font-family:宋体;}
