Dynamic Sortable Table

On this page

With Wappler you can create responsive, sortable data tables. First, you need to create a server action which contains a database query which will be used as a data source.

In App connect panel add new component:

Open the data menu:

And add server connect component:

Then select your server action, which contains the database query:

Select the server action and click the select button:

We will show you how to store the sort order and direction in URL parameters so that on page refresh they won't get lost. Add new component:

Open the state management menu:

And add query manager:

Then, define the query parameters:

Click the add new button:

And select add variable:

We call this query parameter - sort. It will be used to store the column we sort the table by:

Then we add another one:

We call it - dir. It will be used to store the sort order (ascending or descending):

Click save:

Then select your server action and in the properties panel, under input parameters, select the dynamic data picker for the sort parameter:

Pick the sort query parameter we just defined(1) and click save(2):

We do the same for the Dir parameter:

Select the dir query parameter for it:

And then click the add button, where you want to insert the table:

Open the generators menu:

And select table generator:

Select your data source:

This is the database query from your server action:

Then, select the table styling options:

Enable the sortable headers option. This way your table headers become sortable on click:

Select the query manager instance, which we created a few steps back:

And set the sort query parameter in the Sort Parameter menu:

Then select the dir query parameter in the Order Parameter menu:

You can remove columns by selecting them and clicking the remove button. You can also double click the header fields, to edit the text. Click a column number and drag it up/down to rearrange columns:

Click Ok in order to insert the table on the page:

You can see your table, with sortable headers directly in design view:

Select the table in App Structure, then click the Run button if you need to edit it. This will bring the UI so you can edit the options.
