Vim tabular alignment first column different - vim

Question

I’m trying to format tables in LaTeX nicely using the Tabular command, and frequently I’ll want to right-align the leftmost column, then left align everything else. Using :'<,'>Tabularize /&/r1c1l0 almost works, but only on the first column pair; the rest of the table is weirdly aligned almost as if Tabular is repeating that sequence.
How can I write a command that will align the table code without me having to type something like :'<,'>Tabularize /&/r1c1l0c1l0c1l0…?
EDIT: Example table code
\begin{longtable}{>{\bfseries}l >{\scshape}Fl -l -l -l -l -l -l -l -l -l -l}
\toprule
Case & & \SetRowStyle{\scshape} nil & 1sg & 2sg & 3sg & 1du;inc & 2du & 1pl;inc & 1pl;exc & 2pl & 3pl \\
\midrule\endhead
\multirow{4}{*}{Focal} & nat & -a & -ai & -uta & -ima & -iva & -etua & -isa & -ečé & -atá & -amia \\
& sgv & -ena & -enai & -enta & -enima & -eniva & -entua & -enisa & -enčé & -entá & -emia \\
& du & -eva & -evai & -evta & -evima & -eviva & -evtua & -evisa & -evčé & -evtá & -evmia \\
& pl & -esa & -esai & -esta & -esima & -esiva & -estua & -esisa & -esčé & -está & -esmia \\
\midrule
\multirow{4}{*}{Nominative} & nat & -am & -aim & -utam & -imam & -ium & -etum & -isam & -ečem & -atám & -amim \\
& sgv & -enam & -enaim & -entam & -enimam & -enium & -entum & -ensim & -enčem & -entám & -emim \\
& du & -evam & -evaim & -evtam & -evimam & -evium & -evtum & -evsim & -evčem & -evtám & -evmim \\
& pl & -esam & -esaim & -estam & -esimam & -esium & -estum & -essim & -esčem & -estám & -esmim \\
\midrule
\multirow{4}{*}{Absolutive} & nat & -aš & -aiš & -utaš & -imaš & -iuš & -etuš & -isaš & -ečeš & -atáš & -amiš \\
& sgv & -enaš & -enaiš & -entaš & -enimaš & -eniuš & -entuš & -ensiš & -enčeš & -entáš & -emiš \\
& du & -evaš & -evaiš & -evtaš & -evimaš & -eviuš & -evtuš & -evsiš & -evčeš & -evtáš & -evmiš \\
& pl & -esaš & -esaiš & -estaš & -esimaš & -esiuš & -estuš & -essiš & -esčeš & -estáš & -esmiš \\
\bottomrule
\caption{Consonant-final animate noun suffixes\label{tab:nst_animate_consonant_stem_suffixes}}
\end{longtable}
It compiles just fine but I’d like the source code to be formatted somewhat nicer.

You may find vim-easy-align useful.
Try
:'<,'>EasyAlign&mrl*
which is a shorthand notation for
:'<,'>EasyAlign & { 'mode_sequence': 'rl*' }
& tells the plugin to align text using predefined & rule for LaTeX tables
rl* means right, left, left, left, ...
You can adjust left and right margin around the delimiter as follows:
:'<,'>EasyAlign&mrl*l0r1
a shorthand notation for
:'<,'>EasyAlign & { 'mode_sequence': 'rl*', 'left_margin': 0, 'right_margin': 1 }
