Create a table column by column with special border formatting

Create a table column by column with special border formatting

I need to create some tables for a special college report. The data
provided specifies the values column by column.
The user Andrew Swann pointed out, that there is a way to create TeX
tables column by column which was completeley new to me, but would be a
great benefit for my special purpose.
Unfortunately I neither understand those commands nor didn't find a good
documentation for that. What I need is a table with borders around each
single cell except for the first cell and the whole last row. Below is an
example how it would look like using the regular syntax.
Could you please tell me how I can create such a table by building it
columnwise?

\begin{tabular}{|l|l|l|}
\cline{2-3}
\multicolumn{1}{l|}{a} & b & c \\ \hline
d & e & f \\ \hline
g & h & i \\ \hline
\multicolumn{1}{l}{j} &
\multicolumn{1}{l}{k} &
\multicolumn{1}{l}{l} &
\end{tabular}
