    Use v 1.59 (this month) template The “acmart” document class includes the “booktabs” package — ctan.org/pkg/booktabs — for preparing high-quality tables. Table captions are placed above the table. Because tables cannot be split across pages, the best placement for them is typically the top of the page nearest their initial cite.... The contents of the table itself must go in the tabular environment, ......Again, detailed instructions on tabular material are found in the Latex guide anorien.csc.warwick.ac.uk/mirrors/CTAN/macros/latex/contrib/…

    (i) in your mwe is many errors. please make sure that text after % is no manually break into more line (ii) in preamble are missed packages necessary to work your table (iii) please explain what is your problem. in your MWE is no longtable :-(

to long to put in comment ...

  • sorry, i have some issues with installed acmart document class. so i can't test it on my computer how it works
  • in overleaf i see, that [acmsmall]{acmart} generate one column document. however, i'm not sure in this, so please check if my observation is correct.
  • in case, that it generate one column document, you can use longtable,
  • i correct your MWE. it should be as follows:

please, test above MWE in tel us, what is actually your problem. also inform us, if your document have only one column. in this case is possible to use for example ltablex which is combination of longtable and tabularx package.

let me note, that this is your third similar question, which differ only in used \documentclass. please, decide which document class you actually will use.

addendum: in case, that you really need long table and that you have one column document, than try, if the following gives what you after:

  • Sorry sir, I knew that it was my third similar question,actually initially I was asked to make it in IEEE latex format ,now in smart, that's why I am finding difficulty, actually this table formation was very difficult for me, as it contains long equations and its a multipage table, but you helped me a lot continuously, I think this table should work in my ACM small template....thanks, i will check and tell you May 2, 2019 at 5:24
  • @DiptiMishra, if you not attent to publish article in some of avm journals,why you not simply use article?
