How to Reduce Width of IR Link Column in APEX

Interactive Reports (IR) in APEX have a attribute to include a link column:

{% asset_img ir-attribute.png %}

When you run the page the link column takes up more space than necessary:

{% asset_img ir-link-column-default.png %}

You can reduce the width by adding the following CSS to your application: Note width may vary depending on circumstances)

th#LINK,
td[headers=LINK]
{
  width:40px;
}

Column links will now look like:

{% asset_img ir-link-column-reduce.png %}
