After generating your report, have you noticed your tables don't have a title?
Each widget in your template has a "Widget" title, and also has a title for the graph and/or table. This gives you the flexibility to customize your widget and give your graphs and tables very specific titles for your client's to understand.
When you add a new widget to your report, the title in the tables tab defaults to be left blank so you can input your custom title.
Type your title in the box provided and save your template. Then you may also need to just re run your report to see the update.
