Check if a table field’s column has a value

Question

I am using a table field to display credits on a portfolio page. The table field has three columns: hva, hvem and url.

The url should be optional and I want to set up an if statement showing it as a link if it has a value. Is this possible using the table field?

Also, the table field can have multiple rows.

I have tried to set up an if for row.url to see if has a value. And an else for when there is no URL.

{% if entry.credits|length %}
    {% for row in entry.credits %}
        {% if row.url == 0 %}
            <li><span class="bold">{{ row.hva }}:</span> <a href="{{ row.url }}">{{ row.hvem }}</a></li>
        {% else %}
            <li><span class="bold">{{ row.hva }}:</span> {{ row.hvem }}</li>
        {% endif %}
    {% endfor %}
{% endif %}

You were close...

Chaning this:

{% if row.url == 0 %}    

to this:

{% if row.url|length %}

should do it for you.
