Changing data from long to wide format

[overhead_press]

Below I have a table I would like to transform into my second table. The idea is that the row with numbers in col 2 and col 3 is the main row and the rows below that row with null values in col 2 and col 3 belong to that same group. So in my example there are three groups, the rows below the groups I would like to have them as column values, note the column names does not matter. How can I achieve my desired results? Thanks in advance! 

Original table:

Col 1	Col 2	Col 3
MISC PAYMENT	567	56789
Org	[Null]	[Null]
CREDIT	123	12345
XO	[Null]	[Null]
AX	[Null]	[Null]
CREDIT	780	123456
ABC	[Null]	[Null]
MC	[Null]	[Null]

Desired results: 

Col 1	Col 2	Col 3	Col 4	Col 5
MISC PAYMENT	567	56789	Org
CREDIT	123	12345	XO	AX
CREDIT	780	123456	ABC	MC
