How to fit big table in a single page without changes in margins?

Question

I've shown two tables in the below code, one with changes in page margin and other is without change in margin. As per rule I can't change page margin even slightly and I've only one page for this table, and this table is not fitting properly in one page. Please suggest me a way(anyway) to fit this table properly in one page.

\documentclass{llncs}
\usepackage{longtable}
\usepackage[table]{xcolor}
\usepackage{xcolor,colortbl}
\newenvironment{changemargin}[1]{
  \begin{list}{}{
    \setlength{\voffset}{#1}
  }
  \item[]}{\end{list}}
\usepackage{array}
\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
\setcounter{secnumdepth}{3}
\usepackage{enumerate}
\usepackage[T1]{fontenc}
\usepackage[all,cmtip]{xy}
\usepackage{tikz-cd}
\usepackage{enumitem}
\usepackage{changepage}
\usepackage{mathtools}
\usepackage{amsmath}
 \numberwithin{equation}{subsection}
\DeclarePairedDelimiter\floor{\lfloor}{\rfloor}
\usepackage{amsfonts}
\usepackage[normalem]{ulem}

My table doesn't fit; what are my options? – Johannes_B May 13 '17 at 11:52 — Johannes_B, May 13 '17 at 11:52

Here is a solution, using enumitem and nccmath for its \medmath command to have mediums-sized formulae: it allows to reduce the size of the commutative diagrams:

\documentclass{llncs}
\usepackage{longtable}
\usepackage[table]{xcolor}
\newenvironment{changemargin}[1]{
  \begin{list}{}{
    \setlength{\voffset}{#1}
  }
  \item[]}{\end{list}}
\usepackage{array}
\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
\setcounter{secnumdepth}{3}
\usepackage{enumitem}
\usepackage[T1]{fontenc}
\usepackage[all,cmtip]{xy}
\usepackage{tikz-cd}
\usepackage{enumitem}
\usepackage{changepage}
\usepackage{mathtools}
 \numberwithin{equation}{subsection}
\DeclarePairedDelimiter\floor{\lfloor}{\rfloor}

@TanmaySharma - Just delete (or comment out) the instructions \usepackage{showframe} and \renewcommand\ShowFrameLinethickness{0.3pt}. — Mico, May 13 '17 at 17:12
@Mico Could you please help me in getting left side line that is missing in the table. — Tanmay Sharma, May 13 '17 at 17:40
@TanmaySharma - Just curious: Is there a reason for why you're not asking the creator of the answer (@Bernard) to address the missing-left-sideline issue? — Mico, May 13 '17 at 18:08
@Tanmay Sharma: In the tabularx preambles, replace {|@{}X|X|@{}} with {|X|X|}. Sorry for the error in the code. I've fixed the answer. — Bernard, May 13 '17 at 18:09
@Bernard Thank you so much. It works! I don't have enough privileges, otherwise I'll upvote your answer. Right now I can only accept your answer. Thank you once again. — Tanmay Sharma, May 13 '17 at 19:41
