# Vertical alignment in table with figures

Distinguished colleagues, good afternoon.

How can I make the elements of the first column in vertical alignment with the center of the rows?

\begin{landscape}

\begin{tabular}{ccccccc}
$R a_{L_{P}}$  & \begin{tabular}[c]{@{}c@{}}$r=1.00$\\ (Reference Geometry)\end{tabular} & $r=1.05$                                                          & $r=1.10$                                                          & $r=1.20$                                                           & $r=1.50$                                                           & \begin{tabular}[c]{@{}c@{}}$r=1.50$\\ (Convex Profile)\end{tabular} \\

Here's my attempt at this using the tabularray1 package and the \raisebox command2.

\usepackage{graphicx}

\usepackage{tabularray}

\usepackage[margin=2cm]{geometry}

# Remarks

I would recommend converting the command into a macro, but I won't do that for now.

Like this?

• Unfortunately you not provide MWE (Minimal working Example), consequently any information about your document are unknown.
• Since we haven't your pictures (and also don't know their sizes), in MWE below are used draft option to document class, In real document you need to remove it.
• By help of adjustbox package are moved images baselines to the vertical centers.
• For shorter code and common settings for images are use \adjincludegraphics instead of \includegraphics and for them settings defined by \adjustboxset.
• Nicer spacing of images in table is used tblr of tabularray package

If you more prefer landscape environment, than instead rotating package load lanndscape and replace sidewaystable with landscape. Compilation resulz will be similar as before.
