Can't change QTable Column width

[fenchai]

This is what I have that is working ok-ish:
width: 'Npx' does nothing

<template v-slot:body-cell-description="props">
        <q-td :props="props" :style="{ width: '50px', whiteSpace: 'normal' }">
          <div class="tableCell">
            {{ props.value }}
          </div>
        </q-td>
      </template>

What I have tried:
this method from googling

cols: [
{
name: “status”,
align: “left”,
filter: true,
sortable: true,
style: ‘width: 40px’,
type: “string”
},
]
