Django : HTML Table with iterative lists values

Question

I am using Django framework and trying to build a table based on the values i have in a list:

list : [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12], [3, 3, 3, 3]] The table should be as shown below:

The code I have used is :

  html = "<html><body><br>" \
           "<table border=1 ><thead> <tr><th>result 1</th><th>result 2</th><th>result 3</th><th>result 4</th></tr><thead>{% for item in matrix %} {% for secitem in item %} <tr> <td> {{secitem[0]}} </td>  <td> {{secitem[1]}} </td><td> {{secitem[2]}} </td><td> {{secitem[3]}} </td>  </tr>    {% endfor %}{% endfor %} " \
           "</table></body></html>"

I am not able to get the exact table with the required rows in it. Any help is highly appreciated.![enter image description here][1]

I am unable to upload image. However, it should be a 4X4 table with values of list present. — Goutam

You are iterating over a list within a list, yet you are trying to access indices of an item within a list within a list.

Remove the "secitem" loop and access indices of item OR simply iterate over the item.

{% for row in matrix %}
<tr>
    {% for value in row %}
        <td>{{ value }}</td>
    {% endfor %}
</tr>
{% endfor %}

Is there something wrong with this code? I am still unable to get the result in tables: html = "<html><body><br>" \ "<table border=1 ><thead> <tr><th>result 1</th><th>result 2</th><th>result 3</th><th>result 4</th><th>result 5</th></tr><thead>{% for row in matrix %}<tr>{% for value in row %}<td>{{ value }}</td>{% endfor %}</tr>{% endfor %} " \ "</table></body></html>"

or, if you want the headers: <table border=1><tr><th>Col1</th><th>Col2</th><th>Col3</th><th>Col4</th></tr> suggested code </table>

@GoutamAdwant that is correct. What is the output and issues you're still having? Note: if <thead> is present, you should add <tbody> around your primary rows.

@Yuji'Tomita'Tomita I have removed <thead> from the code. The output i am getting is this : s15.postimg.org/vfjpc7597/image.png

@GoutamAdwant to me that looks like you need to compile your template. Rendering a django template in a view should be a separate issue altogether that I assumed you had already accomplished. Are you doing so?
