Hi Marco,
Not much of an angular problem. More of a data-manipulation one. lets see
es6 like:
let tmp = data.reduce((table,elem) => toTable(table,elem),{});
let table = Object.keys(tmp).map(i => tmp[i]);
function toTable(table, elem) {
table[elem.item] = (table[elem.item]||0) + item.qty;
return table;
}
Typed up here in the browser, so there might be a syntax error in somewhere.
Now use a ngRepeat over the resulting table var, and you should be done.
If you have any more questions, do not hesitate to ask.
Regards
Sander
