How to highlight all rows that have the exact same data in multiple columns within a Table?

[Klash Ville]

Titles says it all, if someone could provide me with a simple code to highlight all rows that have the exact same data in multiple columns within Table1 I would be much apreciated

For Example:

1 - 1 - 1 - 1 must be highlighted

1 - 1 - 1 - 2 must NOT be highlighted, only the exact same values in an entire row in multiple columns

Try Conditional Formatting
Assuming data in A1:D2...

Select A1:D2; in Conditional Formatting pick the formula option; insert this formula
=COUNTIF($A1:$D1,A1)=4
pick the format you want
