所有，
我在数据表上使用RowGrouping，对于每个组，我需要对某些列(Encum，Paid，Balance)进行小计，对Column(Encum，Paid，Balance)的所有行进行合计。我对这个Datatable很陌生，无法达到我所需要的结果。这是已使用的代码。我需要显示这些列的3的$ value并在标题中进行小计。
请在这里帮助我，jsfiddle中的代码:jsfiddle.net/6r2pjbg8

"drawCallback": function ( settings ) {
var api = this.api();
var rows = api.rows( {page:'current'} ).nodes();
var last=null;
var colonne = api.row(0).data().length;
var totale = new Array();
totale['Totale']= new Array();
var groupid = -1;
var subtotale = new Array();
api.column(0, {page:'current'} ).data().each( function ( group, i ) {
debugger;
if ( last !== group ) {
S$(rows).eq( i ).before(
'<tr class="group"><td colspan="5">'+group+'</td></tr>'
);
last = group;
}
//sub total
val = api.row(api.row($(rows).eq( i )).index()).data(); //current order index
$.each(val,function(index2,val2){
debugger;
if (typeof subtotale[groupid] =='undefined'){
subtotale[groupid] = new Array();
}
if (typeof subtotale[groupid][index2] =='undefined'){
subtotale[groupid][index2] = 0;
}
if (typeof totale['Totale'][index2] =='undefined'){
totale['Totale'][index2] = 0;
}
// valore = Number(val2.replace('€',"").replace('.',"").replace(',',"."));
subtotale[groupid][index2] += 1;
totale['Totale'][index2] += 2;
});
} );
$('tbody').find('.group').each(function (i,v) {
var rowCount = $(this).nextUntil('.group').length;
//$(this).find('td:first').append($('<span />', { 'class': 'rowCount-grid' }).append($('<b />', { 'text': ' ('+rowCount+')' })));
var subtd = '';
for (var a=0;a<3;a++)
{
subtd += '<td>'+ subtotale[i][a] +'</td>';
}
$(this).append(subtd);
});
}
});
