DataTable in Flutter

Do you ever want show data in table format to your App users in your mobile application.Now, it is easier with Flutter Widget DataTable().

DataTable will take DataColumn() list for table header and Datarow() list for table rows. And each DataRow will take the DataCell().

Example DataTable:

sample Table

DataTable(columns: [    DataColumn(      label: Text("Name"),    ),    DataColumn(      label: Text("Age"),    ),    DataColumn(      label: Text("Year"),    ),  ], rows: [    DataRow(cells: [      DataCell(Text("Varun")),      DataCell(Text("22")),      DataCell(Text("1999")),    ]),    DataRow(cells: [      DataCell(Text("Alexa")),      DataCell(Text("23")),      DataCell(Text("1998")),    ]),    DataRow(cells: [      DataCell(Text("Arjun")),      DataCell(Text("21")),      DataCell(Text("2000")),    ]),  ]);

Anything that goes into a DataCell and DataColumn is a widget.Hence we can show anything in the table.
for eg: adding FlutterLogo() to DataColumn and all DataRows gives

DataTable with Flutter Logo

 DataRow(cells: [      DataCell(Text("Arjun")),      DataCell(Text("21")),      DataCell(Text("2000")),      DataCell(FlutterLogo()),    ]),

we can give option to edit the cell data to the user with onTap() function and we can indicate with showEditIcon:true

 DataCell(        Text("21"),        showEditIcon: true,        onTap: () {},      ),

edit

we can also show data using map;
consider the data:

 var data = <Data>[    Data("varun", "20", "2001"),    Data("varun1", "21", "2000"),    Data("varun2", "23", "1998"),    Data("varun3", "26", "1995"),  ];

then

DataTable(    columns: [      DataColumn(        label: Text("Name"),      ),      DataColumn(        label: Text("Age"),      ),      DataColumn(        label: Text("Year"),      ),      DataColumn(label: FlutterLogo())    ],    rows: data.map((data) {      return DataRow(cells: [        DataCell(Text(data.name)),        DataCell(Text(data.age)),        DataCell(Text(data.year)),        DataCell(FlutterLogo())      ]);    }).toList(),  );

gives the output of
datatablelist
you can play with it codepen
