Installation

Simply install the package through npm

npm i ng-material-treetable --save

Make sure you have the angular material packages installed

npm i @angular/material @angular/cdk @angular/animations --save

import the main module

import { TreetableModule } from 'ng-material-treetable';

@NgModule({
    ...
  imports: [
    ...
    TreetableModule
  ],
  ...
})
export class AppModule { }

and use the component in your template

<treetable [tree]="yourTreeDataStructure"></treetable>

Finally, make sure you import the required material icons font in your styles.css

@import url('https://fonts.googleapis.com/css?family=Roboto:400,700|Material+Icons');

Data Format

The tree object that's rendered by the component can either be a Node<T> or a Node<T>[] where Node<T> is the following interface

import { Node } from 'ng-material-treetable';

interface Node<T> {
  value: T;
  children: Node<T>[];
}

Here's a simple example.

{
  value: {
    name: 'Reports',
    owner: 'Eric',
    protected: true,
    backup: true
  },
  children: [
    {
      value: {
        name: 'Charts',
        owner: 'Stephanie',
        protected: false,
        backup: true
      },
      children: []
    },
    {
      value: {
        name: 'Sales',
        owner: 'Virginia',
        protected: false,
        backup: true
      },
      children: []
    },
    {
      value: {
        name: 'US',
        owner: 'Alison',
        protected: true,
        backup: false
      },
      children: [
        {
          value: {
            name: 'California',
            owner: 'Claire',
            protected: false,
            backup: false
          },
          children: []
        },
        {
          value: {
            name: 'Washington',
            owner: 'Colin',
            protected: false,
            backup: true
          },
          children: [
            {
              value: {
                name: 'Domestic',
                owner: 'Oliver',
                protected: true,
                backup: false
              },
              children: []
            },
            {
              value: {
                name: 'International',
                owner: 'Oliver',
                protected: true,
                backup: true
              },
              children: []
            }
          ]
        }
      ]
    }
  ]
}

Options

Work in Progress...

An option input property can be used to customise the component

import { Node, Options } from 'ng-material-treetable';

<treetable
  [tree]="yourTreeDataStructure"
  [options]="yourOptions">
</treetable>

customColumnOrder

Given a tree data type like

interface Person {
  name: string;
  age: number;
  married: boolean;
}

const tree: Node<Person> = ...

a custom column order can be specified with the following options object

const opts: Options<Person> = {
  customColumnOrder: ['married', 'age', 'name']
}

an incomplete or incorrect customColumnOrder value will result in an error

customColumnOrder: ['married', 'age'] // 'name' missing
customColumnOrder: ['married', 'age', 'name', 'surname'] // 'surname' is not a valid key

Events
