title: Vue ant design select in table
body: <p>I'm adding select component to table, and now i would like to get selected items, but if i add v-model to a-select all my selects select same value, another idea to get index of row and add to select Array, but idk how to get rowIndex in @change event.
  How can i get index of row or get for each a-select it's own v-model?</p>
  
  <pre><code>&lt;a-table
          :columns="columns"
          :dataSource="data"
          :scroll="{ x: 'max-content' }"
          :pagination="{ pageSize: 9 }"&gt;
          &lt;template slot="Client"&gt;
              &lt;a-select v-model="selected" style="width: 200px" @change="handleChange"&gt;
                 &lt;a-select-option v-for="client in getProjects" :key="client" :value="client"&gt;
                    {{client}}
                 &lt;/a-select-option&gt;
              &lt;/a-select&gt;
          &lt;/template&gt;
  &lt;/a-table&gt;
  </code></pre>
