Quasar is a popular Vue UI library for developing good looking Vue apps.
In this article, we’ll take a look at how to create Vue apps with the Quasar UI library.
Custom Table Top
We can change the content of the top of the table by populating the top slot.
For instance, we can write:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<div class="q-pa-md">
<q-table title="Treats" :data="data" :columns="columns" row-key="id">
<template v-slot:top>
<q-btn color="primary" label="Add row" @click="addRow"></q-btn>
<q-btn
class="q-ml-sm"
color="primary"
label="Remove row"
@click="removeRow"
>
</q-btn>
</template>
</q-table>
</div>
</q-layout>
</div>
<script>
const columns = [
{
name: "name",
required: true,
label: "Dessert",
align: "left",
field: (row) => row.name,
format: (val) => `${val}`,
sortable: true
},
{
name: "calories",
align: "center",
label: "Calories",
field: "calories",
sortable: true
},
{ name: "fat", label: "Fat (g)", field: "fat", sortable: true },
{
name: "calcium",
label: "Calcium (%)",
field: "calcium",
sortable: true,
sort: (a, b) => parseInt(a, 10) - parseInt(b, 10)
}
];
const data = [
{
name: "Frozen Yogurt",
calories: 159,
fat: 6.0,
calcium: "14%"
},
{
name: "Ice cream sandwich",
calories: 237,
fat: 9.0,
calcium: "8%"
},
{
name: "Eclair",
calories: 262,
fat: 16.0,
calcium: "6%"
},
{
name: "Honeycomb",
calories: 408,
fat: 3.2,
calcium: "0%"
},
{
name: "Donut",
calories: 452,
fat: 25.0,
calcium: "2%"
},
{
name: "KitKat",
calories: 518,
fat: 26.0,
calcium: "12%"
}
];
new Vue({
el: "#q-app",
data: {
columns,
data
},
methods: {
addRow() {
this.data.push(
this.data[Math.floor(Math.random() * this.data.length)]
);
},
removeRow() {
this.data.splice(Math.floor(Math.random() * this.data.length), 1);
}
}
});
</script>
</body>
</html>
We add 2 buttons into the top slot to add and remove rows from the table respectively.
Custom Table Body Content
We can customize the table body content by populating the body slot:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<div class="q-pa-md">
<q-table
title="Treats"
:data="data"
:columns="columns"
row-key="name"
>
<template v-slot:body="props">
<q-tr :props="props">
<q-td key="name" :props="props">
{{ props.row.name }}
</q-td>
<q-td key="calories" :props="props">
<q-badge color="green">
{{ props.row.calories }}
</q-badge>
</q-td>
<q-td key="fat" :props="props">
<q-badge color="purple">
{{ props.row.fat }}
</q-badge>
</q-td>
<q-td key="calcium" :props="props">
<q-badge color="accent">
{{ props.row.calcium }}
</q-badge>
</q-td>
</q-td>
</q-tr>
</template>
</q-table>
</div>
</q-layout>
</div>
<script>
const columns = [
{
name: "name",
required: true,
label: "Dessert",
align: "left",
field: (row) => row.name,
format: (val) => `${val}`,
sortable: true
},
{
name: "calories",
align: "center",
label: "Calories",
field: "calories",
sortable: true
},
{ name: "fat", label: "Fat (g)", field: "fat", sortable: true },
{
name: "calcium",
label: "Calcium (%)",
field: "calcium",
sortable: true,
sort: (a, b) => parseInt(a, 10) - parseInt(b, 10)
}
];
const data = [
{
name: "Frozen Yogurt",
calories: 159,
fat: 6.0,
calcium: "14%"
},
{
name: "Ice cream sandwich",
calories: 237,
fat: 9.0,
calcium: "8%"
},
{
name: "Eclair",
calories: 262,
fat: 16.0,
calcium: "6%"
},
{
name: "Honeycomb",
calories: 408,
fat: 3.2,
calcium: "0%"
},
{
name: "Donut",
calories: 452,
fat: 25.0,
calcium: "2%"
},
{
name: "KitKat",
calories: 518,
fat: 26.0,
calcium: "12%"
}
];
new Vue({
el: "#q-app",
data: {
columns,
data
},
});
</script>
</body>
</html>
We get the table cell data from the slot props.
And we render the items inside the q-td component however we like.
Conclusion
We can customize the table’s top and body content with the slots provided by Quasar’s q-table component.
