How to center align Flutter DataTable (SfDataGrid)?

In this article, we will show how to center-align Flutter DataTable.

Initialize the SfDataGrid widget with the required properties. By default, the DataGrid occupies the full width and height of its parent widget. To center it within the available space, wrap it in a Center widget and explicitly specify a fixed width and height. This ensures the DataGrid is properly centered on the screen.

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Syncfusion Flutter DataGrid')),
      body: Center(
        child: SizedBox(
          width: 500,
          height: 550,
          child: SfDataGrid(
            source: employeeDataSource,
            columnWidthMode: ColumnWidthMode.fill,
            columns: <GridColumn>[
              GridColumn(
                columnName: 'id',
                label: Container(
                  padding: EdgeInsets.all(16.0),
                  alignment: Alignment.center,
                  child: Text('ID'),
                ),
              ),
              GridColumn(
                columnName: 'name',
                label: Container(
                  padding: EdgeInsets.all(8.0),
                  alignment: Alignment.center,
                  child: Text('Name'),
                ),
              ),
              GridColumn(
                columnName: 'designation',
                label: Container(
                  padding: EdgeInsets.all(8.0),
                  alignment: Alignment.center,
                  child: Text('Designation', overflow: TextOverflow.ellipsis),
                ),
              ),
              GridColumn(
                columnName: 'salary',
                label: Container(
                  padding: EdgeInsets.all(8.0),
                  alignment: Alignment.center,
                  child: Text('Salary'),
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
