怎么给esayUI datagrid列标题名title做修改背景色或字体的操作

重写下面的样式就可以了

.datagrid-header,
.datagrid-td-rownumber {
  background-color: #efefef;
  background: -webkit-linear-gradient(top,#F9F9F9 0,#efefef 100%);
  background: -moz-linear-gradient(top,#F9F9F9 0,#efefef 100%);
  background: -o-linear-gradient(top,#F9F9F9 0,#efefef 100%);
  background: linear-gradient(to bottom,#F9F9F9 0,#efefef 100%);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#F9F9F9,endColorstr=#efefef,GradientType=0);
}
