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()

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

Example DataTable:

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

 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: () {},
      ),

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
