Algorithm: remove ciphertext by columns in the order of appearance of the letters in the key word in the alphabet

If you and I have agreed in advance on the key word COMPUTER and the basic algorithm $--$ solve by inserting plaintext by rows beneath the key word, insert ciphertext by columns in the order of appearance of the letters in the key word in the alphabet $($hint READ the bold text again$-$this is the way to solve this$).$ Fill in the table above using the ciphertext letters listed below:

DEGIOEAODELONIAEHTOLRVTSOFNLEYKRLTL!TFEFULTETIFO

THERE IS AN EXPLANATION POINT IN THE CIPHER TEXT BE SURE TO INCLUDE THAT.

Solve the algorithm by filling in the table above. Type the message below:
