Vuetify data-table row does not expand

I'm building a vuetify <v-data-table> with button icons on the right-most column. The button icons appear when a data row is hovered. I'd like the data row to expand when the row is clicked, but it's not working.

Current codepen implementation here

The code creates a <v-data-table> as follows:

<v-data-table
      :headers="headers"
      :items="desserts"
      item-key="name"
      class="elevation-1"
      :items-per-page="5"
      :expanded.sync="expanded"
>

And this is the slot to expand the row:

<template v-slot:expanded-item="{ headers, item }">
        <td :colspan="headers.length">More info about {{ item.name }}</td>
</template>

I'm hoping someone with vuetify experience can help me get the data table rows to expand when clicked. Thanks!

hey because you want to expand your row maybe you can try the vuetify expansionpanel?

it cloud look something like this

<template v-slot:item="{index, item}">           
   <v-expansion-panels>
    <v-expansion-panel>
     <v-expansion-panel-header>{{ item.name }}</v-expansion-panel-header>
      <v-expansion-panel-content>
       <v-simple-table>
        <template v-slot:default>
         <thead>
          <tr>
           <td>Calories</td>
           <td>Fat (g)</td>
           <td>Carbs (g)</td>
           <td>Protein (g)</td>
           <td>Iron (%)</td>
           </tr>
          </thead>
          <tbody>
           <tr @mouseover="toolsIndex=index" @mouseleave="toolsIndex=null">
            <td @click="expandRow(index)">{{ item.calories }}</td>
            <td @click="expandRow(index)">{{ item.fat }}</td>
            <td @click="expandRow(index)">{{ item.carbs }}</td>
            <td @click="expandRow(index)">{{ item.protein }}</td>
            <td @click="expandRow(index)">{{ item.iron }}</td>
            <td>
             <v-icon
                  v-show="index==toolsIndex"
                  small
                  class="mr-2"
                  @click.stop="dialog = true"
                  >mdi-pencil</v-icon
                >
                <v-icon
                  v-show="index==toolsIndex"
                  small
                  @click.stop="dialog = true"
                  >mdi-delete</v-icon
                >
             </td>
            </tr>
          </tbody>
         </template>
        </v-simple-table>
       </template>
      </v-data-table>
     </v-expansion-panel-content>
    </v-expansion-panel>
  </v-expansion-panels>         
          </template>

just change your code block like below, problem solved here

<template v-slot:item="{index, item, isExpanded, expand}">
            <tr @mouseover="toolsIndex=index" 
                @click="expand(!isExpanded)"
                @mouseleave="toolsIndex=null">
              <td @click="expandRow(index)">{{ item.name }}</td>
              <td @click="expandRow(index)">{{ item.calories }}</td>
              <td @click="expandRow(index)">{{ item.fat }}</td>
              <td @click="expandRow(index)">{{ item.carbs }}</td>
              <td @click="expandRow(index)">{{ item.protein }}</td>
              <td @click="expandRow(index)">{{ item.iron }}</td>
              <td>
                <v-icon
                  v-show="index==toolsIndex"
                  small
                  class="mr-2"
                  @click.stop="dialog = true"
                  >mdi-pencil</v-icon
                >
                <v-icon
                  v-show="index==toolsIndex"
                  small
                  @click.stop="dialog = true"
                  >mdi-delete</v-icon
                >
              </td>
            </tr>
          </template>

You should change your code like this:

 <template v-slot:item="{index, item, isExpanded, expand}">
            <tr 
               @mouseover="toolsIndex=index" 
               @mouseleave="toolsIndex=null" 
               @click="expand(!isExpanded)"
            >
              <td>{{ item.name }}</td>
              <td>{{ item.calories }}</td>
              <td>{{ item.fat }}</td>
              <td>{{ item.carbs }}</td>
              <td>{{ item.protein }}</td>
              <td>{{ item.iron }}</td>
              .....
