Align to center within Grid Column

[sonicviz]

Any clues on how to do this?
It might seem obvious but none of the regular position/align things seem to work.

I have a row
I have a column

  <q-list bordered separator>
    <q-item class="row q-col-gutter-sm justify-center align-center"
    v-for="x in y" :key='x'>
      <div class="col-1"
        v-for="a in b" :key='a'
      > <div class="align-center">{{ x[a] }}</div>
      </div>
    </q-item>
  </q-list>

Am I missing something?

@sonicviz
this works for me to center things.

style="margin-left: auto;margin-right: auto;"

text-center
