coalesce

I have a situation here, my source table is like this

COL1COL2 COL3COL4 COL5COL6 COL7COL8 COL9COL10

12 NULL4 NULL6 NULL8 9NULL

NULLNULL NULL4 NULL6 NULLNULL NULL10

1 NULLNULLNULLNULLNULL7NULL NULLNULL

my output should be selecting first 3 non null values in 3 columns as below

OUT1OUT2 OUT3

12 4

46 10

17 NULL

is there is any way to deal with it ??
