I know there exists a standard code for a Horner scheme. But I would like to get the following tabular.

I've got the next code but I can't find how I get that little vertical line at the right bottom.

```
\begin{tabular}{c|cccc}
& 3 & 2 & -5 & -10 \\
& & & & \\ \hline
& & & &
\end{tabular}
```

I've got another question about this. The number 11 is now shifted to the left, but I want that it's under 16.

```
\begin{tabular}{c|cccc}
& 3 & 2 & -5 & -10 \\
2 & $\downarrow$ & 6 & 16 & 22 \\ \hline
& 3 & 8 & 11 \multicolumn{1}{c|}{} & 12
\end{tabular}
```
