Updating angular.json
Adding jQuery, Popper JS, Bootstrap CSS, and JS -
Add the following lines in scripts array under build section

"node_modules/bootstrap/dist/js/bootstrap.min.js"
Add the following lines in styles array under build section
node_modules/bootstrap/dist/css/bootstrap.min.css
Integrating into Angular Application
import AngularTreeTableModule
in app.module.ts
.
Configuration in Component
Declare the below variables for table initialization
tableData: TreeTableData = null; //Table Data Holder
tableConfig = new TreeTableDataConfig(); //Table Configuration
tableHeaders: TreeTableHeaderObject[] = []; //Table Headers and Property Binding
Declare the below methods to populate dummy data into the table
populateDummyData() {
const data = [];
for (let i = 0; i < 120; i++) {
const row = new TreeTableRow(i + '', { sno: i+1, name: 'John '+(i+1), age: i+1. address: {dno: '1-23'}}, false, null);
data.push(row);
}
this.tableData = new TreeTableData(this.tableConfig);
this.populateHeaders();
this.tableData.data = data;
}
populateHeaders() {
this.tableHeaders.splice(0, this.tableHeaders.length);
this.tableHeaders.push(new TreeTableHeaderObject('Sno', 'sno', null, true));
this.tableHeaders.push(new TreeTableHeaderObject('Name', 'name', null, true));
this.tableHeaders.push(new TreeTableHeaderObject('Age', 'age', null, true));
this.tableHeaders.push(new TreeTableHeaderObject('User Details', '=CONCAT(Name: |||name|||<br/>|||Age: |||age)', null, true));
this.tableHeaders.push(new TreeTableHeaderObject('D.no', 'address.dno', null, true));
this.tableData.headers = this.tableHeaders;
}
Adding View Element in Component View
Add the below tag in Component HTML View
<angular-tree-table [tableData]=”tableData”></angular-tree-table>
With this, you will get the view of basic Table with given data

Expandable Table View
To configure the row as an expandable, we need to configure the table as below
tableConfig = {
showExpandArrows: true, // Showing Arrows each possible row
showExpandAllArrows: true // Expand all button
};
Update the populateDummyData method as below to add Children to row
**populateDummyData**() {
const data = [];
for (let i = 0; i < 120; i++) {
const row = new TreeTableRow(i + '', { sno: i+1, name: 'John '+(i+1), age: i+1}, false, null);
if (i % 10 !== 0) {
row.expandable = true;
const subTableData = new TreeTableData(this.tableConfig); //We can add new config object if required
const subData = [];
for (let j = 0; j < (10 - i % 10); j++) {
const subRow = new TreeTableRow(j + '', { sno: j + 1, name: 'Paul ' + (j + 1), age: j + 1}, false, null);
subData.push(subRow);
}
subTableData.headers = this.tableHeaders; //Using the same headers as parent table, we can use separate if required
subTableData.data = subData;
row.children = subTableData;
}
data.push(row);
}
this.tableData = new TreeTableData(this.tableConfig);
this.populateHeaders();
this.tableData.data = data;
}
