I am stuck with the following problem.

I would like to align numbers based on the decimal. 

The problem is that I have `\mathbf` statements as well as `$^{***}$` or `$^{**}$` or `$^{*}$` in some of the columns. 

Is there a way to align the numbers easily? I provide an example of the table below.

```
 \setlength\LTleft{0pt}            % default: \parindent

\setlength\LTright{0pt}           % default: \fill

  \begin{center}

  \begin{longtable}{@{\extracolsep{\fill}}*{1}{l}*{12}{c}}

\caption{\textbf{Table}}\\\hline
