silahkan buat file reuseableTable.dart lalu salin codingan di bawah
import 'package:flutter/material.dart';

class DataTablePage extends StatelessWidget {

final List<DataColumn> stickyColumns;

final List<DataColumn> columns;

final List<DataRow> stickyRows;

final List<DataRow> rows;

const DataTablePage({

Key? key,

required this.stickyColumns,

required this.columns,

required this.stickyRows,

required this.rows,

}) : super(key: key);

@override

Widget build(BuildContext context) {

// Set a constant color for heading rows

final headingRowColor = MaterialStateProperty.all(Colors.green);

return Row(

children: [

DataTable(

headingRowColor: headingRowColor,

columns: stickyColumns,

rows: stickyRows,

),

Expanded(

child: SingleChildScrollView(

scrollDirection: Axis.horizontal,

child: DataTable(

headingRowColor: headingRowColor,

columns: columns,

rows: rows,

),

],

);

}

Berikut contoh pemanggilannya/pemakaian
DataTablePage(

stickyColumns: const [

DataColumn(

label: Text('Sticky'),

),

],

stickyRows: List.generate(

10,

(index) {

return DataRow(

cells: [

DataCell(

Text('Sticky $index'),

),

],

);

},

),

columns: List.generate(

8,

(index) {

return DataColumn(

label: Text('header $index'),

);

},

),

rows: List.generate(10, (index) {

return DataRow(cells: [

DataCell(

Text('data$index'),

),

DataCell(

Text('data$index'),

),

DataCell(

Text('data$index'),

),

DataCell(

Text('data$index'),
