I was trying to make this layout using `subfigure`-s from `subcaption` package.

This is what I wanted.

```
+-----------+
|           |
|           |   +-----------+
|    A      |   |           |
|           |   |           |
|           |   |           |
+-----------+   |           |
    (a)         |     C     |
                |           |
+-----------+   |           |
|           |   |           |
|    B      |   |           |
|           |   +-----------+
+-----------+        (c)
    (b)
    
          Main caption
```

How can this be achieved?

I have currently adapted a snippet that I had found online and made it like this:

```
\documentclass{article} 
\usepackage{subcaption} 
\usepackage{graphicx} 
\begin{document}
\begin{figure}
{
	\centering\begin{subfigure}[b]{0.5\linewidth}
		\centering\includegraphics[width=.5\linewidth]{example-image-a}
		\caption{\label{figA}Fig A}
	\end{subfigure}%\hfill

	\begin{subfigure}[b]{0.5\linewidth}
		\centering\includegraphics[width=.69\linewidth]{example-image-b}
		\caption{\label{figB}Fig B}
	\end{subfigure}\vspace{10pt}
}\hfill%
	\begin{subfigure}[b]{\linewidth}
		\centering\includegraphics[width=5cm]{example-image-c}
		\caption{\label{figC} Fig C}
	\end{subfigure}
	\caption{Main caption}
\end{figure}
\end{document}
```

But that's showing up as:

![subfig.png](/image?hash=51f3788ea749e3f59536815492337a5f3fa3d569d1341670db154093fcacb5d4)

In my actual use case, I have got tables instead of images though.
Does it make a difference for the example?
