去掉table的默认样式 reset.css

table{    width:100%;    text-align:center;/*文本居中*/    border-collapse:collapse; /*表格的边框合并，如果相邻，则共用一个边框*/    border-spacing:0; /*设置行与单元格边框的间距。当表格边框独立（即border-collapse:separate;）此属性才起作用*/}table td{    word-break: break-all; /*允许在字内换行,即单词可分*/    word-wrap:break-word;/*允许长单词或URL地址换行*/    border-right:1px solid #939598;    border-bottom:1px solid #939598;     font:500 14px Arial;}

下面推荐使用 reset.css 清除默认样式，解决不同浏览器的兼容性问题。
