Aligning Text in a Table (various alignments in the column)

Question

I need to set up a table with three columns.

The first two columns have a width of 7.2 cm and the last has a width of 1.5 cm.

I would like text in the first row of the columns to be centred, but then the text in the first and third columns will remain centred, but the second column is aligned to the left.

I tried the tabularx suggestion on here, but can't set the column widths, let alone see how I can change the second column to left aligned.

Answer 1

Various alignment in tables is very easy with tblr environment of tabularray package:

\documentclass{article}

\usepackage[a4paper,margin=1cm]{geometry}
\usepackage{tabularray}

\begin{document}

\begin{table}[h]
\centering
\begin{tblr}{
  colspec = {Q[7.2cm,c]|Q[7.2cm,l]|Q[1.5cm,c]},
  row{1} = {c}, hlines,
}
  Column 1 & Column 2 & Col 3 \\
  The text in this column needs to be centred and allow for text wrapping and will include equations
           & Text in this column needs to be aligned to the left and needs to allow for text wrapping
                      & no wrap \\
\end{tblr}
\end{table}

\end{document}
