# Solution 1 :

I did it concatenating the id, month and year:

function get_conts() {
var rows = document.getElementById('one').rows,
len = rows.length,
i,
cell_id = 1,
cell_month = 2,
cell_year = 3,
count = 0,
cell;

for (i = 1; i < len; i++) {
cellvalue_id = rows[i].cells[cell_id];
cellvalue_month = rows[i].cells[cell_month];
cellvalue_year = rows[i].cells[cell_year];
get_workers(cellvalue_id.innerHTML + "_" + cellvalue_month.innerHTML + "_" + cellvalue_year.innerHTML);
}
}

function get_workers(id_ent) {
var rows = document.getElementById('two').rows,
len = rows.length,
i,
cell_id = 1,
cell_month = 2,
cell_year = 3,
count = 0,
cell;

for (i = 1; i < len; i++) {
cellvalue_id = rows[i].cells[cell_id];
cellvalue_month = rows[i].cells[cell_month];
cellvalue_year = rows[i].cells[cell_year];
concatenated_text = cellvalue_id.innerHTML + "_" + cellvalue_month.innerHTML + "_" + cellvalue_year.innerHTML);

if (concatenated_text === id_ent.toString()) {
count++;
}
}

var total_workers = document.getElementById('total_' + id_ent).innerHTML;

document.getElementById('total_' + id_ent).innerHTML = (total_workers - count).toString();
console.log(total_workers + "-" + count);
}

get_conts();

# Problem :

I need to print a table with some total and then a second table with detailed events. Then I need to change the total of each total of the first table considering the number of rows of the second table.

I did it considering just one criteria of the second table. I need to consider 3 criteria (ID, MONTH and YEAR).

function get_conts() {
var rows = document.getElementById('one').rows,
len = rows.length,
i,
cellNum = 1,
count = 0,
cell;

for (i = 1; i < len; i++) {
cell = rows[i].cells[cellNum];
get_workers(cell.innerHTML);
console.log(cell.innerHTML);
}
}

function get_workers(id_ent) {
var rows = document.getElementById('two').rows,
len = rows.length,
i,
cellNum = 1,
count = 0,
cell;

for (i = 1; i < len; i++) {
cell = rows[i].cells[cellNum];

if (cell.innerHTML === id_ent.toString()) {
count++;
}
}

var total_workers = document.getElementById('total_' + id_ent).innerHTML;

document.getElementById('total_' + id_ent).innerHTML = (total_workers - count).toString();
console.log(total_workers + "-" + count);
}

get_conts();

EDIT 1: I think concatenating ID, MONTH and YEAR it will work.
