import AngularTreeTableModule in app.module.ts.
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}, 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.tableData.headers = this.tableHeaders; } 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
Basic Tree Table Screenshot
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; } Expandable Table Screenshot
