Using documentation example of v-data-table getting Error TypeError: Cannot create property 'isRootInsert' on string ... using latest Vuetify 2.3.x -- unable to reproduce in codepen. Anyone had this happen? Was working fine before.. I nuked node-modules and even rebuilt using classic vue-cli with vuetify?

Make sure in your Vue files to import components.
import { Vue, Component } from 'vue-property-decorator'
After you import your components from vue-property-decorator in all your Vue files.
Make sure you register your components in all your Vue files as well like the snippet below
#Component({
components: {
},
...
})
Make sure all your pages in router must add #Component.
if one of pages doesn't contain #Component,
it will not work out.

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
:footer-props="{'items-per-page-options':[15, 30, 50, 100, -1]}"
...>
Edit:
You can add one more property in :footer-props attribute value object.
'items-per-page-all-text':'Todos'

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>

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);}

return {

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)
}
}
I am using Vuetify 2 to create a data table for an app. In the data table I have custom headers, with slots, including "text", "value", "sortable". Is there a slot I can add to specify the font color and font size I want for each header? If I add a class parameter, how do I add the CSS specifics needed for the headers?
Example code I am using:
data: () => ({
dataFilters: {},
selectedRows: [],
gridConfig: {
records: [],
loading: true,
options: {
itemsPerPageOptions: [10, 25, 50, 100],
totalPages: 0,
itemsPerPage: 10,
page: 1,
descending: false,
},
headers: [
{
text: '__HEADER__MENU__',
value: `__HEADER__MENU__`,
sortable: false,
},
Thank you!
Yes it is possible to set custom color to vuetify data-table header and font size
You need to use class property in headers object
headers: [
{
text: '__HEADER__MENU__',
value: `__HEADER__MENU__`,
sortable: false,
class: "success--text title"
},
success--text class changes the color of your header
title increase the font size of you header, read all the fonts typography and colors in Vuetify
For dynamically setting the headers classes, use created hook to loop through this.headers and set the headers
