How to display different column data as tool tip in ag grid pivot mode?

Issue

var ColDef = [{
    headerName: "colA",
    field: 'colA',
    rowGroup: true
  },
  {
    headerName: "colB",
    field: 'colB',
    pivot: true,
    enablePivot: true
  },
  {
    headerName: "colC",
    field: 'colC',
    rowGroup: true
  },
  {
    field: 'colD',
    aggFunc: 'first',
    valueFormatter: currencyFormatter,
    tooltip: function(params) {
      return (params.valueFormatted);
    },
  },
  {
    field: 'comment'
  },
  {
    field: 'colF'
  }
];
function currencyFormatter(params) {
  return params.value;
}

above code is from different question. it works but i want to use different ‘comment’ field as tool tip to current ‘colD’ . also this is a group and pivot agGrid,if it is normal grid this is not a problem. I would appreciate any ideas for group and pivot agGrid?

Solution

    var ColDef = [{
        headerName: "colA",
        field: 'colA',
        rowGroup: true
      },
      {
        headerName: "colB",
        field: 'colB',
        pivot: true,
        enablePivot: true
      },
      {
        headerName: "colC",
        field: 'colC',
        rowGroup: true
      },
      {
        field: 'colD',
        aggFunc: 'last',
    tooltipValueGetter: commentTooltipValueGetter
      },
      {
        field: 'comment'
      },
      {
        field: 'colF'
      }
    ];


    function commentTooltipValueGetter(params) {
    const colB = params.colDef.pivotKeys[0];
    var model = params.api.getDisplayedRowAtIndex(params.rowIndex);
    for (var i = 0; i < model.allLeafChildren.length ; i++) {
        if (model.allLeafChildren[i].data.colB=== colB) {
          return model.allLeafChildren[i].data.comments;
                                                       }
                                             }
  }
