onClick Event on anchor tag not possible.? Custom button on the table not possible?

I am using the ng2-smart-table. I want to add a new button to All my columns in the table. It seems it is not possible in any way. So i looked through some issues and found out people are using custom anchor tags which is apparently possible. I tried using the anchor tag and the href property does take me to a new page. But i dont want to move to any other page i want to raise a function from my component onClick of either the button or the anchor tag. Is this going to be possible? If so, please help me out.

Summing up in simple words:
1) How to add a custom button to the smart table.?
2) How to assign onclick event to an anchor () tag.?
