I have created a data-table and i need the data in a child-component if i click on a row.

In Console log i get the row data but i can not read it in the child-compontent. 
I'm very new to Angular, i understand to write some easy strings to child, but not an Array or an Object. 

I created a stackblitz for my problem, if you open the console and do a click on a row you get the object, how to write object data in the html of the child-component?!
