Twig : table total all row and columns - symfony

Question

I have a table with 10 rows and 10 columns with int values; I need the total to be print at 11th row, also i need to total and print at columns.
Example :
cell(1x11) = row1+row2+row3...row10;
cell(2x11) = row1+row2+row3...row10;
and
cell(11x1) = col1+col2+col3...col10;
cell(11x2) = col1+col2+col3...col10;
How can i do this easily.
Required result :
<table>
<tr>
<th></th>
<th>One</th>
<th>Two</th>
<th>Three</th>
<th>Total</th>
</tr>
<tr>
<td></td>
<td>1</td>
<td>2</td>
<td>3</td>
<td>6</td>
</tr>
<tr>
<td></td>
<td>1</td>
<td>2</td>
<td>3</td>
<td>6</td>
</tr>
<tr>
<td></td>
<td>1</td>
<td>2</td>
<td>3</td>
<td>6</td>
</tr>
<tr>
<th>Total</th>
<td>3</td>
<td>6</td>
<td>9</td>
<td>18</td>
</tr>
</table>
My actual twig code:
`
{% set len = entities|length %}
{% set len_e = exams|length %}
{% if len_e != null and len_e is not empty and len_e > 0 %}
<div class="table-responsive">
<table id="FZUserExam" class="table table-striped table-bordered">

<tr>
<th rowspan="2">SUBJECT</th>
<th rowspan="2">Max<br/>Marks</th>
{% for i in 1..len_e %}
{% if i == 1 %}
{% set terms = exams[0].term %}
{% set x = 1 %}
{% else %}
{% set name = exams[i-1].term %}
{% if name == terms %}
{% set x = x+1 %}
{% else %}
<th colspan="{{x+1}}">{{ terms }}</th>
{% set terms = exams[i-1].term %}
{% set x = 1 %}

{% endif %}
{% if i == len_e %}

Answer 1

I don't know what data structure you're using to memorize your ints, but you could start with something like this:
<table>
{% for r in rows %}
<tr>
{% set rowTotal = 0 %}
{% for c in r.columns %}
{% set rowTotal = rowTotal + c.value %}
<td>{{ c.value }}</td>
{% endfor %}
<td>{{ rowTotal }}</td>
</tr>
{% endfor %}
</table>
