How to set border for Flutter Data Table?
The Syncfusion Flutter Data Table widget provides support to set the border i.e grid lines by using following properties,
- SfDataGrid.gridLinesVisibility: To set the grid lines for the cells other than header and stacked header cells.
- SfDataGrid.headerGridLinesVisibility: To set the grid lines of header and stacked header cells.
Set grid lines for data cells
By default, DataGrid shows horizontal grid lines. The following example shows how to set vertical and horizontal grid lines.
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Syncfusion Flutter DataGrid'),
),
body: SfDataGrid(
source: employeeDataSource,
gridLinesVisibility: GridLinesVisibility.both,
headerGridLinesVisibility: GridLinesVisibility.both,
columnWidthMode: ColumnWidthMode.fill,
columns: <GridColumn>[
GridColumn(
columnName: 'id',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text(
'ID',
))),
GridColumn(
columnName: 'name',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text('Name'))),
GridColumn(
columnName: 'designation',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text(
'Designation',
overflow: TextOverflow.ellipsis,
))),
GridColumn(
columnName: 'salary',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text('Salary'))),
],
),
);
}
Set grid lines for header cells
By default, DataGrid shows horizontal grid lines. The following example shows how to set vertical and horizontal grid lines to header cells.
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Syncfusion Flutter DataGrid'),
),
body: SfDataGrid(
source: employeeDataSource,
gridLinesVisibility: GridLinesVisibility.both,
headerGridLinesVisibility: GridLinesVisibility.both,
columnWidthMode: ColumnWidthMode.fill,
columns: <GridColumn>[
GridColumn(
columnName: 'id',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text(
'ID',
))),
GridColumn(
columnName: 'name',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text('Name'))),
GridColumn(
columnName: 'designation',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text(
'Designation',
overflow: TextOverflow.ellipsis,
))),
GridColumn(
columnName: 'salary',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text('Salary'))),
],
),
);
}
Set outer border for DataGrid
By default, the bottom border for datagrid will be shown. To show another border i.e. top,left and right, you can wrap the SfDataGrid inside the Container and set the required borders for container.
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Syncfusion Flutter DataGrid'),
),
body: Container(
decoration: BoxDecoration(
border: Border(
right:
BorderSide(width: 1, color: Color.fromRGBO(0, 0, 0, 0.26)),
top:
BorderSide(width: 1, color: Color.fromRGBO(0, 0, 0, 0.26)),
bottom:
BorderSide(width: 1, color: Color.fromRGBO(0, 0, 0, 0.26)),
left: BorderSide(
width: 1, color: Color.fromRGBO(0, 0, 0, 0.26)))),
child: SfDataGrid(
source: employeeDataSource,
columnWidthMode: ColumnWidthMode.fill,
columns: <GridColumn>[
GridColumn(
columnName: 'id',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text(
'ID',
))),
GridColumn(
columnName: 'name',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text('Name'))),
GridColumn(
columnName: 'designation',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text(
'Designation',
overflow: TextOverflow.ellipsis,
))),
GridColumn(
columnName: 'salary',
label: Container(
padding: EdgeInsets.symmetric(horizontal: 16.0),
alignment: Alignment.center,
child: Text('Salary'))),
],
),
),
);
}
