行悬浮样式修改

.ant-table-tbody > tr:hover:not(.ant-table-expanded-row) > td {
	background-color: #F1F6FD!important;
}
.ant-table-body .ant-table-row-hover{
	background: #F1F6FD!important;
}
.ant-table-body .ant-table-row-hover>td{
	background: #F1F6FD!important;
}
 

如果有固定列的需要添加以下样式：

.ant-table-fixed .ant-table-row-hover{
  background: #E5E9EE!important;
}
.ant-table-fixed .ant-table-row-hover>td{
	background: #E5E9EE!important;
}
