  • You have to pass here to blur the focused cell of the table after a value of any of cells has been changed.
  • works the same way, but func receives current and current state of the cell ( ) as parameters, so you can create an outpur based on them.
  • The only exception, that you have to use and props to redefine height of the header and rows to not broke the scroll of the table.
