How can I highlight the highest value in each row of a table?

Question

In Google Sheets, I would like to highlight the max value in each row of a table.

I tried using conditional formatting, but without any success so far.

Answer 1

For each column do the following:

1) Select column or range (say it is A)
2) Select conditional formatting
3) Select in "Format rules" "custom formula is"
4) Enter the formula: =A1=MAX(A$1:A$6)

Here A1 - starting cell
A6 - ending cell

Answer 2

custom formula is:

=(A1=MAX($A1:$D1))*(A1<>"")
