bootstarp table 열 가로 확장(동적 열)

총괄적으로 말하자면 먼저 데이터베이스에서 표시할 열을 조회하고 표두로 맞춘다.그리고 표시할 데이터를 조회하고 테이블에 연결합니다. 주의해야 할 것은 헤더의 filed 값은 데이터의 필드 이름과 같아야 합니다. 저는 ArrayList에 저장된 그룹을 사용했습니다. 그룹 아래 표를 데이터의 필드 이름으로 사용하기 때문에 헤더의 filed도 0, 1, 2, 3 으로 해야 합니다.이름을 지정합니다.방법이 스마트하지 않은 것 같은데???

html에 table 하나만 넣으면 ok:

class="table table-striped" id="class_mark" align="center"
       striped="true" data-height="360" data-click-to-select="true">
