How to show different types of drill downs in a powerful table

Looking for some ideas to a problem we have in a corporate application and how did you solve them.

There will be a powerful table (inside a widget that user will create on its own, but thats not relevant), from where you will be able to navigate to different levels in different ways:

From one field or from one row
1. Drill down (New table connected to chosen field/row)
2. Report
3. Cross site navigation

Take into consideration, that this is a financial very powerful application, so there will be already a lot of numbers and colours (red, orange, green) in the table. As well some kind of learning curve is expected in order to make work more efficient.

My thoughts

For navigation from the field I was thinking about underline the value, but then the question is if I should show different kind of navigations (drilldown, report, cross site) with some kind of icons, but then on each field, or only in the header, but this might be quite crowded.

From the row, I thought about right click and then to show options or icons at the end of the row, that can be the same as for fields.
