Get started with the Table API
Note: Where possible, use qlik-embed and qlik/api rather than this framework.
The Table API allows developers to work with tabular data returned from the Qlik associative engine without having deeper knowledge of internal constructs, like for example, a Hypercube.
The qlik.app.createTable
method is the entry point to the Table API. It
creates a table object that wraps the hypercube. A table object of type QTable
is returned. It is initially empty but will eventually contain data. The table
object will be updated when selection state changes. Notification is sent when
data is available and will be triggered after each update. To receive
notification, bind a listener on OnData
of a QTable instance.
Initialization using the hypercube of the current visualization:
const table = qlik.table( this );
const listener = () => {
const rowCount = table.rowCount;
const colCount = table.colCount;
table.OnData.unbind( listener ); // unregister the listener when notification
// is no longer needed.
};
table.OnData.bind( listener ); // bind the listener
Your main script, based on using AngularJS:
if ( !this.$scope.table ) => {
this.$scope.table = qlik.table( this );
In your AngularJS template:
<tr ng-repeat="row in table.rows">
<td ng-repeat="cell in row.cells"> {{cell.qText}} </td>;
</tr>
Examples of use
Learn what you can do with the Table API.
Export the hypercube
Example 1:
This example creates a button that exports the entire hypercube data when pressed.
const qTable = qlik.table(this);
const $exportButton = $( document.createElement('button'));
$exportButton.html('Export');
$exportButton.bind('click', ( ) => {
qTable.exportData({download: true});
});
$element.append($exportButton);
Example 2:
This example is using AngularJS in a visualization extension
Main script:
...
paint: ( ) => {
//set up scope.table
if ( !this.$scope.table ) {
this.$scope.table = qlik.table( this );
}
}
...
Angular template:
<button ng-click="table.exportData({download:true})">Create Excel file</button>
Get more hypercube data
This example gets more data for your hypercube and is based on using AngularJS in a visualization extension.
Main script:
...
paint: ( ) => {
//set up scope.table
if ( !this.$scope.table ) {
this.$scope.table = qlik.table( this );
}
}
...
Angular template:
<button ng-if="data.rowcount>data.rows.length" ng-click="data.getMoreData()">More</button>
