Tips for customizing a single row in v-data-table? [Vuetify]

Question

Tips for customizing a single row in v-data-table? [Vuetify]

My goal is to change the background color of a specific row that contains an entry matching the value of lowestEntry.

<v-col cols="8">
        <v-data-table
          :loading="loadEntryTable"
          loading-text="Searching for data..."
          :headers="this.entryheaders"
          :items="this.stockentries"
          :items-per-page="10"
        >
        //I have attempted using the v-slot.item without success
</v-data-table>
</v-col>

I am looking to highlight the background color of the tr element to green when

item.id_entry == lowestEntry["id_entry"]

.

Answer №1

For those using the latest versions of vuetify, you now have access to the item-class property within the v-data-table. This property allows you to pass the item as an argument to the callback function.

<v-data-table
....
:item-class="itemRowBackground"
></v-data-table>

You can then define a function that determines the class name:

methods: {
  itemRowBackground: function (item) {
     return item.protein > 4.2 ? 'style-1' : 'style-2'
  }
}

Next, create the classes for style-1 and style-2:

.style-1 {
  background-color: rgb(215,215,44)
}
.style-2 {
  background-color: rgb(114,114,67)
}

Here is a code pen example that demonstrates this concept codepen example

Note: If :item-class is not supported in your version of Vuetify or if you require more control over the row styling beyond just applying a class, you will need to utilize the item slot and manually bind the class/style.

To accomplish this, target the item slot and manually bind the class to the row:

<v-data-table>
    <template #item="{ item }">
      <tr :class="item.id_entry === lowestEntry['id_entry'] ? 'custom-bg' : ''">
        <!-- Define all your <td> elements here. -->
      </tr> 
    </template>
<v-data-table>

Alternatively, you can use

:class="customRowClass(item, lowestEntry)"

and implement the customRowClass method:

methods: {
  customRowClass (item, lowestEntry) {
  return item.id_entry === lowestEntry['id_entry'] ? 'custom-bg' : ''
  }
}

Following totalhacks' suggestion, the updated vuetifys item-class code is as follows:

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  methods: {
    row_classes(item) {
        if (item.calories < 200) {
          return "orange";
        } 
    }
  },
  data () {
    return {
      singleSelect: false,
      selected: [],
      headers: [{text: 'Dessert', value: 'name'},{ text: 'Calories', value: 'calories' },],
      desserts: [{name: 'Frozen Yogurt',calories: 159,},{name: 'Ice cream sandwich',calories: 237,},{name: 'Eclair',calories: 262,},{name: 'Cupcake',calories: 305,},],
    }
  },
})

.orange {
  background-color: orange;
}

Answer №3

If you are working with Vuetify version 3, utilize the row-props property to customize the appearance of a row, for example:

 <v-data-table :headers="headers" :items="some_items" :sort-by="[{ key: 'id', order: 'desc' }]"   :row-props="colorRowItem" >

Here is how the JavaScript function may look like (greatly simplified):

function colorRowItem(item) {
  if (item.item.some_property != undefined && item.item.some_property.includes("Freigegeben")) {
    return { class: 'some_text' };
  } 
}

Answer №4

To change the background color of the tr, you can utilize v-bind: on the class attribute and create a method to handle the color change.

Check out the code snippet below for a working example:

new Vue({
  el: '#app',
  //vuetify: new Vuetify(),
  methods: {
    getClass(calories) {
      //You can define your logic here to determine the class based on the calorie count
      if (calories == 237) return 'orange';
      else if (calories == 305) return 'green';
    },
  },
  data() {
    return {
      headers: JSON.parse('[{"text":"Dessert (100g serving)","align":"left","sortable":false,"value":"name"},{"text":"Calories","value":"calories"},{"text":"Fat (g)","value":"fat"},{"text":"Carbs (g)","value":"carbs"},{"text":"Protein (g)","value":"protein"},{"text":"Iron (%)","value":"iron"}]'),
      desserts: JSON.parse('[{"name":"Frozen Yogurt","calories":159,"fat":6,"carbs":24,"protein":4,"iron":"1%"},{"name":"Ice cream sandwich","calories":237,"fat":9,"carbs":37,"protein":4.3,"iron":"1%"},{"name":"Eclair","calories":262,"fat":16,"carbs":23,"protein":6,"iron":"7%"},{"name":"Cupcake","calories":305,"fat":3.7,"carbs":67,"protein":4.3,"iron":"8%"},{"name":"Gingerbread","calories":356,"fat":16,"carbs":49,"protein":3.9,"iron":"16%"},{"name":"Jelly bean","calories":375,"fat":0,"carbs":94,"protein":0,"iron":"0%"},{"name":"Lollipop","calories":392,"fat":0.2,"carbs":98,"protein":0,"iron":"2%"},{"name":"Honeycomb","calories":408,"fat":3.2,"carbs":87,"protein":6.5,"iron":"45%"},{"name":"Donut","calories":452,"fat":25,"carbs":51,"protein":4.9,"iron":"22%"},{"name":"KitKat","calories":518,"fat":26,"carbs":65,"protein":7,"iron":"6%"}]')
