Hi, how can I print out the a,b,c,d,e,f in html side?

html
<div class='table_row'>
    <div class='table_small' v-for="item in Numlist" :key="item">
      <div class='table_cell'>Header</div>
      <div class='table_cell'>{{item}}</div>
    </div>
  </div>
Array
Numlist:[
                {
                    a:2,
                    b:3,
                },
                {
                    c:4,
                    d:5,
                },
                {
                    e:6,
                    f:7,
                },
            ],

How to iterate over an object and get access to the key and the value at the same time is documented here:

<li v-for="(value, key) in myObject">
  {{ key }}: {{ value }}
</li>
