  • GridPanel row spanning (well, sort of...)
  • The current GridPanel implementation doesn't support row spanning, because the rows aren't part of the same table.

  • Code:
  • Ext.onReady(function(){

    보고서를 작성할 때 자주 이런 수요가 있다. 바로 한 차원이나 여러 차원이 같은 값을 한 번만 표시하고 통합하는 수요이다. Extjsgrid는 기본적으로 이런 기능을 가지고 있지 않다. 우리 스스로 변통적인 방식으로 실현해야 한다. 그의 홈페이지에서 어떤 사람이 아래의 해결 방안을 제시했다. 비록 일부 결함이 있지만 간신히 기능을 실현할 수 있다.코드의 실현을 보면 그는 1열 값과 1열 값을 합친 것을 발견했다. 만약에 몇 열의 같은 값을 합치려면 무력하다. 생각해 보니 변통 방식을 취하기로 결정했다. 합치려는 몇 열의 값을 하나의 키 값으로 하고 키 값이 같은 줄에 대해서는 더 이상 표시하지 않기 때문에 아래의 실현이 있다. 물론 여기는 여전히 중간에 있을 수 없다.

    if(rowIndex>0){ return store.getAt(rowIndex - 1).get('key')!=store.getAt(rowIndex).get('key') ? value : ''; }else{ return value; } }, dataIndex: 'publishdate'
