\begin{document}

\noindent
\begin{tabular*}{\textwidth}[t]{l@{\extracolsep{\fill}}r}
Line 1 (left) & Line 1 (right) \\
Line 2 (left) & Line 2 (right) \\
\end{tabular*}
\vspace*{\fill}
\end{document}
where the \extracolsep command is to add elastic width to the table column2.
Besides, we can use @{} to suppress the small space before the first column and that after the last column3:

\begin{document}
\vspace*{\fill}
\noindent
\begin{tabular*}{\textwidth}[t]{@{}l@{\extracolsep{\fill}}r@{}}
Line 1 (left) & Line 1 (right) \\
Line 2 (left) & Line 2 (right) \\
\end{tabular*}
\vspace*{\fill}
\end{document}
Method 3: tabularx environment
\begin{tabularx}{⟨width⟩}[⟨pos⟩]{⟨preamble⟩}
The arguments of tabularx are essentially the same as those of the standard tabular* environment. However rather than adding space between the columns to achieve the desired width, it adjusts the widths of some of the columns. The columns which are affected by the tabularx environment should be denoted with the letter X in the preamble argument. The X column specification will be converted to p{⟨some value⟩} once the correct column width has been calculated.4

\end{tabularx}

We can use \tabularnewline to specify the line spacing:

\textboxt{\centering Center 2}
\hspace{-9px}

\vspace*{\fill}

Note that the nuance between \hfil and \hfill command6.
