?將計算列值綁定到數據表數據模型

}, {
a: 2,
b: 4
}, {
a: 3,
b: 8
}, {
a: 4,
b: 10
}, ]
var table = $('#dt').DataTable({
data: data,
columns: [{
title: "a",
data: "a"
}, {
title: "b",
data: "b"
}, {
title: "c",
data: null
}],
aoColumnDefs: [{
aTargets: [2],
mRender: function(data, type, row) {
return row.a + row.b;
}
}]
});
$('#log').click(function() {
var data = table.rows().data();
// first row only
// logged -> {a: 1, b: 2}
// desired -> {a: 1, b: 2, c: 3}
console.log(data[0]);
