[Tex/LaTex] Insert figure in a table, how to align figures with text in a table

Question

I am inserting multiple figures into a table, and would like to make the following change:

1. center the text (1st column) in the cell (all the text currently are at the bottom)

2. center the figures (2nd and 3rd column) so that it doesn't cut the horizontal lines. The figures all have slightly different size. Is there a way to auto-adjust the height of each row so that all figures will fit it?

3. If possible, I would like to show some of the long text in two rows. For example, instead of :

   Inverting op-amp (linear amplifier)
   

   I want it to be in two lines, both horizontally centered in the cell:

   Inverting op-amp
   (linear amplifier)
   

Any suggestions would be highly appreciated! Thanks!

Here is my latex code:

\begin{table}[ht] 
\centering 
\begin{tabular}{  p{4.5cm}  p{5cm}  p{5cm}  }      % centered columns (3 columns) 
\hline\hline                                      %inserts double horizontal lines

Answer 1

I made \Includegraphics (cap I) to insert a picture shifted down half its height. I also used some \linebreaks and \raggedrights.

I also added some gap above/below the pictures, as requested with \addstackgap. I can take an optional argument (default 3pt) to specify the gap.

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{stackengine}
\newsavebox\mybox
\newcommand\Includegraphics[2][]{\sbox{\mybox}{%
  \includegraphics[#1]{#2}}\abovebaseline[-.5\ht\mybox]{%
  \addstackgap{\usebox{\mybox}}}}
