Datatable vuetify select multiple rows (Shift+Click) - vue.js

Question

I am using Datatable from Vuetify 1.5.x
Have enabled the checkboxes so that multiple rows can be selected, I would like to be able to select with Shift + Click so that I don't have to click on each checkbox exact same as Gmail works.
It wouldn't be difficult to do if I had a row id that changes by the sort or if the rows array was reordered when the data table is sorted. But none of these seem to work.
Has anyone achieve this with vuetify datatable?
<template v-slot:items="props">
<tr :active="props.selected" #click="selectRow(props);">
<td>
<v-layout>
<v-flex>
<v-checkbox
:input-value="props.selected"
primary
hide-details
:class="{ 'red--text': props.item.was_modified_recently == 1 }"
></v-checkbox>
</v-flex>
</td>
</tr>
</template>

Answer 1

I actually had to solve this today.
My solution relied on using the item-selected hook and method that performs the bulk selection.
methods: {
bulkSelect({ item: b, value }) {
const { selectedRows, current, shiftKeyOn } = this;
if (selectedRows.length == 1 && value == true && shiftKeyOn) {
const [a] = selectedRows;
let start = current.findIndex((item) => item == a);
let end = current.findIndex((item) => item == b);
if (start - end > 0) {
let temp = start;
start = end;
end = temp;
}
for (let i = start; i <= end; i++) {
selectedRows.push(current[i]);
}
}
},
}
So that's the meat of it. There's other housekeeping details like keeping track of when shift is being held down, and preventing the browser from highlighting the text of the table when holding down shift and clicking the second row.
I made a codepen showing this functioning here.

Answer 3

Vuetify added prepend-item slot that lets you add a custom item before listing items by which we can add "select all"
Please check the example in codepen on pretend-item for select all checkboxes

Answer 4

I've got the same case as you faced.
First of all, you got to add another events (keyboard events) on the <tr>
tag and pass the props as argument.
And then use slice to the items array for determined range of the selected items you want.
In my case, i've stored the selected array inside vuex store.
hoped i can helped ;)
<template v-slot:items="props">
<tr :active="props.selected" #click.shift="useShift(props)" #click="selectRow(props)">
<td>
<v-layout>
<v-flex>
<v-checkbox
:input-value="props.selected"
primary
hide-details
:class="{ 'red--text': props.item.was_modified_recently == 1 }"
></v-checkbox>
</v-flex>
</td>
</tr>
</template>
export default {
methods:{
...mapMutations(["setSelected"]),
useShift({ index }) {
this.setSelected(
this.items.slice(
this.items.findIndex(el => {
return this.selected.find(v => v.track.id == el.track.id);
}),
index
)
);
},
}
}
