Pagebreak in subfloated tabulars using the subfig package

Question

I am trying to create a table in a landscape environment containing several subtables which content exceeds one page. Therefore a pagebreak within the table to separate the subtables on multiple pages is necessary.

The main problem here is that I can't use a longtable environment.

I've been using the table environment and putting tabulars inside, but the table environment isn't pagebreaking even using the \ContinuedFloat command.

I've tried using a figure environment and putting tabulars inside, but the figure environment isn't pagebreaking even using the \ContinuedFloat command,

        random ref \ref{tab:c}

using \newline or \\ between the tabulars gives me:

"There's no line here to end. \newline"

This is what it looks like:

Answer 1

• The code, which you provide, is not possible to test. Missed is type of document class, it has typing errors in document preamble, also it has errors in document body, where are missed \end{landscape}s. Please always test document example (MWE: Minimal Working Example) before you upload here, if it can be compiled and eliminate all found typing errors.
• As I mentioned in comments, the command \ContinuedFloat is used that float caption, where it is used, has the same number as in the previous the same type of float. Your use seems to be wrong, since you haven't floats of the same type before floats, where you use it. Consequently your captions looks like :

• It seems that you confuse the function of \label and \ref or subref. Later two are used for referring something with label, which indicate the last used referable counters (as are table, figure, section etc). If you like to have this functionality, you need first to insert labels after such counters. For example,: \section{...}\label{sec:my section} and the refer it as for example See section \ref{sec:my section}. In your case you need add labels after or in captions in subfloats and after float captions. See MWE below.
• it is not clear, why in where you should use \\ in your code. For put some \subfloat below previous one, just insert empty lines between them.

Answer 2

Thanks to @Zarko I got to understand the \ContinuedFloat command and build several table envirnonments with tabulars that keep counting up (alphabetical) using the \ContinuedFloat command and stoped the tables from counting up using \addtocounter[table]{0}. To refer to subfloats, I am using \label instead of \subref due to some questionmark errors I still don't undestand.
