Vuetify data table show last page when loaded - vue.js

How can I add prop "page" so that the table shows the last page when loaded. The number of items is variable. Should I do items.lenght/items-per-page or is there any better way?
<v-data-table
:headers="headers"
:items="items"
:search="search"
multi-sort
must-sort
:sort-by="['date', 'number']"
class="elevation-1"
:items-per-page="10"
:footer-props="{
showFirstLastPage:true,
}"
:loading="loading"
height="540"
></v-data-table>

#grimdbx as per your above comments it is correct, you've taken the right try, you just need to set the page property with the computed result
The computed property always retruns the last page number on page load
computed: {
lastPage() {return Math.ceil(this.items.length/10);}
}
here instead of this.itemsPerPage you can replace with 10, since you
have harcoded the items per page as per your above code
the final working code looks like
<div id="app">
<v-app id="inspire">
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"
class="elevation-1"
:page="lastPage"
></v-data-table>
</v-app>
</div>
new Vue({
el: '#app',
vuetify: new Vuetify(),
computed: {
lastPage() {return Math.ceil(this.desserts.length/5);}
},
data () {
return {
headers: [
{
text: 'Dessert (100g serving)',
align: 'start',
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' },

{

How to change text to all in v-table vuetify?

Currently I can change the number of options but what I don't know is how to change all to Todos, What can I do to change it ?
<v-data-table

You can add one more property in :footer-props attribute value object.

How to add pagination code to data table in vue js?

I'm utilizing v-data-table in a vue component, looking through the documentation it wasn't clear to me how to utilize built in pagination in the data table and how to invoke code for the pagination . I tried to look through some of the blogs but still not clear.
<template>
<v-data-table
:page="page"
:pageCount="numOfPages"
:headers="headers"
...
</template>
<script>
export default {
name: "DataTableSample",
data() {
return {
...
},
watch: {
options: {
handler() {
this.getData();
},
},
deep: true,
},
methods: {
load(){
//load data
...
},
mounted(){
this.getData();
},
};
</script>
Not sure what does this statement means it wasn't clear to me how to utilize built in pagination in the data table and how to invoke code for the pagination ?
But <v-data-table> providing pagination by default. Here is the demo :

How can I iterate between dynamic columns with v-slot in Vuetify

I have dynamically changing columns in data-table. For example an col1, col2, col3-value column. How can I made dynamically the <template v-slot:item.col1="item"> and <template v-slot:item.col2="item">....
You can add multiple templates in your table. So you can just define one for every col in your table.
Here is a working example with the deserts example in the vuetify API.
<template>
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"
class="elevation-1"
>
<template v-slot:item.calories=" { item }">
{{ item.calories.toFixed(2) }}
</template>
<template v-slot:item.fat=" { item }">
{{ item.fat.toFixed(1) }}
</template>
<template v-slot:item.carbs=" { item }">
{{ item.carbs.toFixed(3) }}
</template>
</v-data-table>
</template>
<script>
export default {

Vuetify data table get selected item

I have a v-data-table that has Show-select,
I want to get the data of what items I selected, at least alert the first column value upon check

this is just an example of what I recently found (code not mine),
this code can detect if all checkbox selected
Use v-model instead of :value to allow modification of selected variable when you try to select some items. Then check the this.selected's length inside the enterSelect function.
<v-data-table
v-model="selected"
#input="enterSelect()"
...
>...</v-data-table>
methods: {
enterSelect() {
console.log(this.selected.map(e => e.name)); // logs all the selected items.
if (this.selected.length == this.itemsPerPage) {
alert('selected all')
}
}
}
For example you want to get the names of the rows, here's how to get them.
methods: {
enterSelect(values) {
var names = values.map(function(value){ return value.name })
console.log(names)
}
}

Vuetify table doesn't accept input

Is it possible to add vuetify inputs to vuetify table?
The only way that I found to add data to a table is by using JSON content.
Is it possible to overide/config vuetify so it adds data to the table like Material Design does?
This is how I call my table
<template>
<v-data-table
:headers="headers"
:items="desserts"
:items-per-page="5"

It is possible to add vuetify inputs(v-text-field component) to data table, you can use v-slot:body to override the table content
