Trying to move headings from single lines to filling an extra column

[AkisM]

My input table looks like this

ColumnA	ColumnB	ColumnC	ColumnD	ColumnE
HeadingA	[Null]	[Null]	[Null]	[Null]
SubheadingA	[Null]	[Null]	[Null]	[Null]
Value A1	Value B1	Value C1	Value D1	Value E1
Value A2	Value B2	Value C2	Value D2	Value E2
HeadingB	[Null]	[Null]	[Null]	[Null]
Value A3	Value B3	Value C3	Value D3	Value E3

So sometimes there's only 1 main heading, sometimes there's both a heading and a subheading. I would like to create 2 separate columns for headings and subheading, as shown below:

Heading	Subheading	ColumnA	ColumnB	ColumnC	ColumnD	ColumnE
HeadingA	[Null]	[Null]	[Null]	[Null]	[Null]	[Null]
HeadingA	SubheadingA	[Null]	[Null]	[Null]	[Null]	[Null]
HeadingA	SubheadingA	Value A1	Value B1	Value C1	Value D1	Value E1
HeadingA	SubheadingA	Value A2	Value B2	Value C2	Value D2	Value E2
HeadingB	[Null]	[Null]	[Null]	[Null]	[Null]	[Null]
HeadingB	[Null]	Value A3	Value B3	Value C3	Value D3	Value E3

There is a large number of headings/subheadings with data following them. Any ideas how to achieve the above transformation? I feel like it is simple but can't quite point my finger to it without some complex multi-row formulas.

Hi @AkisM,

I believe this is what you're trying to achieve?

@Jonathan-Sherman Hi, not quite. Value A is lost in the workflow above. All values must be kept intact, as shown in Table 2 in my original post.

Hi @AkisM,

In that case i've made a small change, I think this is now what you're trying to achieve?

Hi @Jonathan-Sherman , not exactly, because the headings/subheadings can be any word, not those words specifically. So using those words as flags won't work. But I get the point of the workflow now, I will just use isNull on the value columns as the flag and it should work fine. Thanks for your help.
