[Tex/LaTex] How to fit large sideways table with Equations/References on A4

equationstables

I have a big Table with long equations and references in some of the entries which overflow the margin. I want to decrease the column width in the table and fit the table better on the page. I decrease font size to decrease complications but it is not sustainable.
Pseudocode

  1. Normal size font.
  2. Have more vertical space in the table.
  3. Decrease the column width.
  4. More rows per cell entry.
  5. Extra spacing.

Fig. 1 .tex file, Fig. 2 The big table with long equations looks where I would like the table to take more vertical space and fit the page better, Fig. 3 Output of Masi's first code and my edit for long equations, Fig. 4 Output of Zarko's first code and my edit for long equations.

where the equations entries do not get nicely presented in the columns but go over other columns, how to fix this by making the equations to continue on the next line?

Optional remarks

  • Better example with more challenging Math symbols etc integrals here about Math in a table
  • You can likely remove \hspace*{-2cm} because negative spacing may not be needed anymore, at least, I think the third column looks funny in Fig. 1. See here about general \hspace spacing
