css样式导致table合并表格rowspan和colspan失败

 .standard_table_tbody {
/* 	display: block; */
    height: calc( 100% - 30px);
   /*  overflow-y: auto; */
   overflow-x: hidden;
    overflow-y: auto;
}

.standard_table .standard_table_thead,.standard_table_tbody tr {
  /*   display: table; */
    width: 100%;
  /*   table-layout: fixed; */
}
