remove table header row

I have the attached table which I wish to

1) Remove the header row.

2) duplicate the second column and append to end, making a third column

3) convert resulting n x 3 structure to a text file.

I have tried converting the table to an array, and then duplicating the second column and appending it to the end making a gthord coliumn, without much luck

Any help greatly appreciated

Should show your work when you've tried something that seems like should but doesn't...it's really quite a straightforward task--tables really do simplify a lot of machinations, particularly when have differing data types as here, for example, between datetime and double.

tst=AUDCAD1d(1:10,:);                             % again, only a little is as good as a whole lot...
tst.New=tst.Open;                                 % make a new column with content of second
writetable(tst,'AUD.csv','WriteVariableNames',0)  % write a csv file without header...

See what we gots...

>> type AUD.csv

20190501095955 ,0.94473,0.94473
20190501100000 ,0.9447,0.9447

20190501100020 ,0.9447,0.9447
20190501100025 ,0.94475,0.94475
20190501100030 ,0.94474,0.94474
20190501100035 ,0.94476,0.94476

looks to satisfy requirements to me... :)

Excepting looks like there's an extra space on the time data...hmmm, let's see---

>> tst.Var1.Format
ans =
    'yyyyMMddHHmmss '
>> 

and indeed, there is. Might want to clean that up altho it may not hurt depending on the use of the file.

Having stumbled onto the other Q? after this, where you took the A preceding that literally in making an unneccessary tst variable mimicking my code, note that the ONLY purpose for it here is just as in that answer -- simply to have a small dataset for demo purposes so could show the results without having to subscript a subset -- 10 elements is just as good to illustrate syntax are 10,000 but the same syntax works on the whole array just as well as the subset, too...

Thank you. WIll rseolve extra space issue, if indeed it is an issue

[dpb]

All it would take is to go back to where you created the variable and get the output format string correct there...do it right the first time instead of having to clean up later.

Done. Thank you

Glad to help... :)
