How to make this table better looking

tablestabularx

Everything is very squished together, does anybody have any suggestions on what I can do?

Here is my code for the table:

\begin{table}[h!]
\centering
\begin{tabular}{|c|c|c|c|c|c|c|c|c|}
\hline
\textit{\textbf{l (m)}} & \textit{\textbf{$\overline{t}$$_{10}$}\:(s)}} & \textit{\textbf{$\Delta t_{10}\:(s)$}} & \textit{\textbf{$T\:(s)$}} & \textit{\textbf{$\Delta T\:(s)$}} & \textit{\textbf{$l^2$\:$(m^2)$}} & \textit{\textbf{$T^2\:(m\:s^2)$}} & \textit{\textbf{$\Delta T^2\:l\:(m\:s^2)$}} & \textit{\textbf{$\sigma \: (s)$}} \\ \hline
0.450                   & 15.414                                        & 0.1739                                 & 1.541                      & 0.01739                           & 0.2025                                          & 1.069                             & 0.02412                                     & 0.1168                            \\ \hline

I would round numbers, for example to four decimals

[Tex/LaTex] How to get multiple multirows in a table

I believe your problem is that you didn't put enough empty cells for the following lines. A multirow will allow content to occupy space, but doesn't actually create the cells that are under it. I rewrote your code aligning everything to illustrate that.

\begin{tabular}{l r | l || r r}
Vzorka & Výskyty & Algoritmus & Porovnania & Prístupy \\ \hline 
\multirow{5}{*}{Gabriel} & \multirow{5}{*}{8} & NAIVE BINARY          & 158   & 44 \\
                         &                    & NAIVE BINARY_LCP      & 174   & 92 \\
                         &                    & NAIVE INTERPOLATION   & 168   & 78 \\
                         &                    & LESS NAIVE BINARY     & 98    & 26 \\
                         &                    & LESS NAIVE BINARY_LCP & 124   & 58 \\ \hline

[Tex/LaTex] In a multi-column table, is there a way to change only SOME text in a specific column (and not the entire column) to be bold or italic

Environment tabularx is already be used, only the usage of the column type X is missing. Also it seems the entries should be vertically centered, this can be achieved by the redefinition of \tabularxcolumn to internally use column type m instead of p. Also the example uses the lines of package booktabs.

\documentclass{article}
\usepackage{array}
\usepackage{booktabs}
\usepackage{caption}
\usepackage{multirow}
\usepackage{tabularx}

\begin{document}
\begin{table}
  \centering
  \caption{My caption}
  \label{my-label}
  \renewcommand*{\tabularxcolumn}[1]{m{#1}}
  \begin{tabularx}{\linewidth}{
