The table view gives you an overview of all your budget data sorted by group. The table shows the planned expenses and revenues, the actual expenses and revenues, and a comparison between actual and planned budget.
Another way to identify budget overruns is to check the status column. It shows you whether your project is within budget or not:
= Project is on budget, i.e. the actual expenses are within the planned budget.
= Actual expenses are higher than planned expenses and you need to control your budget.
