I am trying to reproduce this lowercase k with some mathbb font
I have tried using the bbm font, bbold font and mathds without success. I either get
that is not what I am looking for.
I was able to reproduce the desired symbol with \Bbbk but I read that the package \Bbb is out of date and should be avoided.
Essentially these symbols seem to be available in the MathTime Professional 2 Fonts. In particular page 35 of the user guide gives a complete alphabet of "curly" capital letters including these symbols:
Narrow columns are always difficult to typeset with justification that, on the other hand, makes little sense with typewriter type.
So we can add \raggedright to avoid justification: it'll make the text in the cell flush to the left margin, but not with the right margin.
Thus you can do
\begin{tabular}{
|>{\ttfamily\raggedright}p{0.14\textwidth}
|>{\ttfamily\raggedright}p{0.12\textwidth}
|>{\ttfamily\raggedright\arraybackslash}p{0.62\textwidth}
|}
\hline
...
\end{tabular}
The \arraybackslash in the last column specification is needed because otherwise you can't end the row with \\ (\raggedright redefines it). See the manual of the array package.
If all the tabular is to be typeset in typewriter type, also adding a \ttfamily declaration before it and protected in a group could do, but I believe that this way is better, since it allows more flexibility; for instance you could want to add a new column with different type.

The command
\Bbbthat used to be part ofamsfontshas been deprecated in favor of\mathbb. However,\Bbbkis still the command for the blackboard bold lowercase k and is defined inamssymb.The command
\Bbb{A}produces a warningbut the command
\Bbbkis perfectly fine.
