主要CSS代码
#lineTd {
background: #f0f0f6 url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lIHgxPSIwIiB5MT0iMCIgeDI9IjEwMCUiIHkyPSIxMDAlIiBzdHJva2U9ImJsYWNrIiBzdHJva2Utd2lkdGg9IjEiLz48L3N2Zz4=) no-repeat 100% center;
}
其中PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lIHgxPSIwIiB5MT0iMCIgeDI9IjEwMCUiIHkyPSIxMDAlIiBzdHJva2U9ImJsYWNrIiBzdHJva2Utd2lkdGg9IjEiLz48L3N2Zz4=
是base64加密后的代码，未加密的代码如下：
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%"><line x1="0" y1="0" x2="100%" y2="100%" stroke="#b0b0b0" stroke-width="1"/></svg>
在线加解密
如果需要修改颜色，修改svg的strok属性即可即可
