Custom re-order of columns

[#1]

My jsl script produces the following table which is the combination of summary,split and update functions.

The first few columns have actual mesureamnts for variuos test for past four months and week wise for the current month(new week gets added every sunday). The last 4 columns are expected values for each month for each test.The following are two things I'm trying-

Also my script already has 250 lines so trying to do this in a few lies of code.

1.Rename last 4 columns as Expected,MM08 and so on..The jsl I wrote doesnt work.Mostly because the last four columns(result of update function) get locked.I wrote a jsl to unlock these but that doesnt work too.

for(f=1,f<= Nitems(colNamesList),f++,
	if(word(1,colNamesList[f]) == "N",
		Column(colNamesList[f])<< set name(
			"Expected," || word(2,colNamesList[f])
		)
	)
);

2.I need tp reorder columns such that Actual and expected values for a month are side by side.I re-arrange column function doesnt have a custom oredr option.

Current table -

Test Name	Actual, MM08	Actual, MM09	Actual, MM10	Actual, MM11 One	Actual, MM11 Two	Actual, MM11 Three	N, MM08	N, MM09	N, MM10	N, MM11
Test A	0.22	1	0.9981	1	1	1	0	6	6	6
Test B		1	1	0	0.5169	0	0	4	6	6
Test C	3.38901E-15	0.9853	0.9978	1	1	1	2	4	4	4
Test D	1.54046E-14						10	0	0	0
Test E	7.00209E-14	0.4101	0.7707	0	0	0	8	8	6	6
Test F	3.18277E-13	0.5581	0.7378	0.21955	0.40945	0.7491	6	4	4	4
Test AA	1.44671E-12	1	1	1	1	1	2	2	2	2
Test BC	6.57597E-12	1	1	0.8657	0.5169	1	4	4	4	4
Test CA	2.98908E-11						2	0	0	0

Expected output-

Test Name	Actual, MM08	Expected, MM08	Actual, MM09	Expected, MM09	Actual, MM10	Expected, MM10	Actual, MM11 One	Actual, MM11 Two	Actual, MM11 Three	Expected, MM11
Test A	0.22	0	1	6	0.9981	6	1	1	1	6
Test B		0	1	4	1	6	0	0.5169	0	6
Test C	3.38901E-15	2	0.9853	4	0.9978	4	1	1	1	4
Test D	1.54046E-14	10		0		0				0
Test E	7.00209E-14	8	0.4101	8	0.7707	6	0	0	0	6
Test F	3.18277E-13	6	0.5581	4	0.7378	4	0.21955	0.40945	0.7491	4
Test AA	1.44671E-12	2	1	2	1	2	1	1	1	2
Test BC	6.57597E-12	4	1	4	1	4	0.8657	0.5169	1	4
Test CA	2.98908E-11	2		0		0				0

I think my second problem can be resolved by naming columns in the format MM08,Actual and so on.

If I do this I can re-arrange columns by column name to have actual and expected columns side by side.

But still not able to programatically rename last four columns since they are locked.

If there is any better way,please suggest.
