bootstrap 打印时表格颜色设置

.table-bordered > thead > tr > th, 
.table-bordered > tbody > tr > th, 
.table-bordered > tfoot > tr > th, 
.table-bordered > thead > tr > td, 
.table-bordered > tbody > tr > td, 
.table-bordered > tfoot > tr > td{
	border:1px solid #000 !important;//重点在这里
}

这个css要在boot的css引用之后再用。
