How to change the two switch data with click with Vuejs-CodePudding

Please can someone teach me the method to swap two different data on click

For example, we have a data

data() {
        return {

          data_one: [
            {
              name: "Simo",
              age: "32"
            }
          ],

          data_two: [
            {
              name: "Lisa",
              age: "25"
            }
          ],

        }
      },

then I want to put this data on v-for, and I want to add two buttons to swap from data_one and data_two and display data_one as default.

<button @click="change_to_data_one">Data 1<button>
<button @click="change_to_data_two">Data 2<button>

<li v-for="item in data_one">{{item.name}} - {{item.age}}<li>
