Hello,

I need the footer showing the right values… Is there a way?

also you can implement own footer calculation algorithm.

e.g. balance calculation

webix.ui.datafilter.balanceColumn = webix.extend({
    refresh: function(master, node, value) {
        var result = 0, _val;
        var prefix = value.columnId.substr(0, value.columnId.length - 7);
        master.data.each(function(obj) {
            if (!obj || obj.$group || obj.$footer) return;
            _val = (obj[prefix + "Debit"] || 0) * 1 - (obj[prefix + "Credit"] || 0) * 1;
            if (isFinite(_val)) result += _val;
        });
        if (value.format)
            result = value.format(result);
        if (value.template)
            result = value.template({ value: result });
        node.firstChild.style.textAlign = "right";
        node.firstChild.innerHTML = result;
    }
}, webix.ui.datafilter.summColumn);

Hello!
And thanks for your message.
I have a unfortunately more complicated sample
and it is the combination with this discussion

Here is what I would need:

The footer should show the right value.

Thanks again!
