数据表上的RowGrouping和Subtotal

全部，我在数据表上使用RowGrouping，对于每个组，我需要对列（Encum，Paid，Balance）的所有行（Encum，Paid，Balance）和Total的所有行执行小计。 我对这个数据表很新，并且无法达到我需要的结果。 这是代码已经使用过。 我需要显示这些列的$ 3值，并在标题处进行小计。 请帮帮我，jsfiddle中的代码：jsfiddle.net/6r2pjbg8

var table = S$('#EncumbranceSummaryTable').DataTable({ "columnDefs": [ { "visible": false, "targets":0 } ], "stateSave": false, "stateDuration": 60*60*24*365, "data" : POnbrsDetails, "columns":[ {"sTitle": "PO #", "data": "PO_Nbr" }, {"sTitle": "FY", "data": "FY" }, {"sTitle": "LN", "data": "LN" }, {"sTitle": "F/O/A","data":"FOA"}, {"sTitle": "Project ID", "data": "Proj_ID" }, {"sTitle": "Srce Type", "data": "Srce_Type" }, {"sTitle": "Encumbrance","data":"Encum_Amt"}, {"sTitle": "Paid","data":"Paid"}, {"sTitle": "Balance", "data": "Balance" } ], "drawCallback": function ( settings ) { var api = this.api(); var rows = api.rows( {page:'current'} ).nodes(); var last=null; var colonne = api.row(0).data().length; var totale = new Array(); totale['Totale']= new Array(); var groupid = -1; var subtotale = new Array(); api.column(0, {page:'current'} ).data().each( function ( group, i ) { debugger; if ( last !== group ) { S$(rows).eq( i ).before( ''+group+'' ); 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($('', { 'class': 'rowCount-grid' }).append($('', { 'text': ' ('+rowCount+')' }))); var subtd = ''; for (var a=0;a<3;a++) { subtd += ''+ subtotale[i][a] +''; } $(this).append(subtd); }); } });

这对你有用吗？
