Table Widget in Flutter is used to show our data in a structured format.
If we want our data to be shown horizontally, we prefer using the Row widget.
If we want to display our data in a single column, we prefer using Column Widget.
When we want to display the data horizontally as well as vertically, the Table widget is the one that is preferred.

import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: MyHomePage(), debugShowCheckedModeBanner: false, ); } } class MyHomePage extends StatefulWidget { @override _MyHomePageState createState() => _MyHomePageState(); } class _MyHomePageState extends State<MyHomePage> { @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title:Text("Table Widget"), backgroundColor: Colors.amberAccent, ), body: Column( children:<Widget>[ Padding( padding: const EdgeInsets.all(8.0), child: Text("Student Table",style: TextStyle(fontWeight:FontWeight.bold,fontSize: 20.0),), ), SizedBox(height: 20.0), Padding( padding: const EdgeInsets.all(8.0), child: Table( children: [ TableRow( children: [ Text("1",style: TextStyle(fontSize: 15.0),), Text("Ajay",style: TextStyle(fontSize: 15.0),), Text("80",style: TextStyle(fontSize: 15.0),), ] ), TableRow( children: [ Text("2",style: TextStyle(fontSize: 15.0),), Text("Aniket",style: TextStyle(fontSize: 15.0),), Text("88",style: TextStyle(fontSize: 15.0),), ] ), TableRow( children: [ Text("3",style: TextStyle(fontSize: 15.0),), Text("Anurag",style: TextStyle(fontSize: 15.0),), Text("50",style: TextStyle(fontSize: 15.0),), ] ), ], ), ), ] ), ); } } |
This is the basic structure of our app after writing out the basic code, but we know that it is not looking good
So, in order to make our UI look better, we will add a border to the table with the help of Border property.

Table( border: TableBorder.all(color: Colors.lightBlueAccent,width: 2.0), children: [ TableRow( children: [ Text("1",style: TextStyle(fontSize: 15.0),), Text("Ajay",style: TextStyle(fontSize: 15.0),), Text("80",style: TextStyle(fontSize: 15.0),), ] ), TableRow( children: [ Text("2",style: TextStyle(fontSize: 15.0),), Text("Aniket",style: TextStyle(fontSize: 15.0),), Text("88",style: TextStyle(fontSize: 15.0),), ] ), TableRow( children: [ Text("3",style: TextStyle(fontSize: 15.0),), Text("Anurag",style: TextStyle(fontSize: 15.0),), Text("50",style: TextStyle(fontSize: 15.0),), ] ), ], ), |
For providing different column widths to each column we have a property named columnWidths

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
Table( columnWidths: { 0: FlexColumnWidth(2), 1: FlexColumnWidth(4), 2: FlexColumnWidth(4), }, border: TableBorder.all(color: Colors.lightBlueAccent,width: 2.0), children: [ TableRow( children: [ Text("1",style: TextStyle(fontSize: 15.0),), Text("Ajay",style: TextStyle(fontSize: 15.0),), Text("80",style: TextStyle(fontSize: 15.0),), ] ), TableRow( children: [ Text("2",style: TextStyle(fontSize: 15.0),), Text("Aniket",style: TextStyle(fontSize: 15.0),), Text("88",style: TextStyle(fontSize: 15.0),), ] ), TableRow( children: [ Text("3",style: TextStyle(fontSize: 15.0),), Text("Anurag",style: TextStyle(fontSize: 15.0),), Text("50",style: TextStyle(fontSize: 15.0),), ] ), ], ), |
As a result, we will get the columns with different column widths.
