直接使用css写即可

#td{

background:#FFFFFF url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lIHgxPSIwIiB5MT0iMCIgeDI9IjEwMCUiIHkyPSIxMDAlIiBzdHJva2U9IiNmMGYwZjIiIHN0cm9rZS13aWR0aD0iMSIvPjwvc3ZnPg==) no-repeat 100% center;

}

或者直接写在单元格style中：

<td style="background:#FFFFFF url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lIHgxPSIwIiB5MT0iMCIgeDI9IjEwMCUiIHkyPSIxMDAlIiBzdHJva2U9IiNmMGYwZjIiIHN0cm9rZS13aWR0aD0iMSIvPjwvc3ZnPg==) no-repeat 100% center;">

其中：

PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lIHgxPSIwIiB5MT0iMCIgeDI9IjEwMCUiIHkyPSIxMDAlIiBzdHJva2U9ImJsYWNrIiBzdHJva2Utd2lkdGg9IjEiLz48L3N2Zz4=

是base64加密后的代码，解密后如下：
