What are data tables in Vuetify?

Data tables in Vuetify

Data tables in Vuetify are components that provide a way to display, sort, filter, and paginate data in a tabular format. These tables are highly customizable and can handle a wide variety of data types and structures. They are designed to be responsive, accessible, and efficient, making them suitable for both simple and complex data presentation needs.

Let's look at some of the key features of Vuetify data tables:

• Sorting: Allows to sort the columns of the data table in ascending or descending order.

• Filtering: Allows to filter the data based on the user input.

• Pagination: Allows to break large datasets into manageable pages.

• Selectable rows: Allows to select the rows for further actions.

• Customizable columns: Allows to dynamically add, remove, or customize the columns.

Creating data tables in Vuetify

Let's see how we can create data tables in Vuetify.

Step 1: Install Vuetify using the following npm command:

Step 2: Set up a basic Vue.js project, if not already done, as follows:

Step 3: Once our project is set up, add Vuetify to it as follows:

Step 4: Once Vuetify is added to our project, we can create the data table using the v-data-table component as follows:

In line 2, :items is a Vue directive that binds the items property (a data variable) from the component's script section to the v-data-table component. This directive tells Vue to dynamically use the data stored in items to populate the table's rows.

Step 4: Add a script that will have the definition of items as follows:

This setup creates a simple Vuetify data table displaying names, emails, and roles. We can expand this with additional features like sorting, filtering, and pagination as needed.

Example

Let's look at an example demonstrating a Vuetify data table. Click the “Run” button to execute the example.

The code above displays a data table with four columns: Name, Calories, Fat(g) and Carbohydrates(g). This table demonstrates the use of various Vuetify features such as filtering, sorting, pagination, extendable rows, and selectable rows.

Code explanation

The code in App.vue can be divided into three sections—template, script and style. Let's dive into the template and the script section.

Template section

• Lines 3–31: Inside <v-app>, there's a <v-data-table> component. This component displays tabular data.

• Lines 4–10: Various props like headers, items, search, pagination, expanded, and selected are bound to the respective data properties in the Vue instance.

  • Lines 4–5: :headers and :items props bind to arrays of objects representing table headers and data rows, respectively.

  • Line 6: :search prop binds to a search query string used to filter table data.

  • Line 7: :pagination.sync binds to a pagination object with properties for page number, items per page, and total items.

  • Lines 9–10: v-model:expanded and v-model:selected are used for managing expanded rows and selected rows, respectively.

• Line 11: item-value="name" specifies which property of the item object should be used as a unique identifier for each row.

• Lines 12–13: show-expand and show-select enable features to expand rows and select rows, respectively.

• Lines 16–21: Inside <v-data-table>, there's a <template v-slot:top> which contains a text field used for searching/filtering the table.

• Lines 23–29: Another template <template v-slot:expanded-row> is used to customize the expanded row content.

Script section

The script section contains a Vue.js component definition using export default {}.

• Lines 37–71: Inside the data() function, initial data properties like headers, items, search, pagination, expanded, and selected are defined and returned.

  • headers and items are arrays containing objects representing table headers and data rows, respectively.

  • search is initialized as an empty string to store the search query.

  • pagination object contains properties for page number, items per page, and total items.

  • expanded and selected are arrays used to manage expanded rows and selected rows, respectively.
