Answer 1

You can simply add a widget to this package in each row. and this example used is in the same package with some changes to accept widget.
here is the example code
main.dart
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_web_data_table/web_data_table.dart';
import 'sample_data.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
late String _sortColumnName;
late bool _sortAscending;
List<String>? _filterTexts;
bool _willSearch = true;
Timer? _timer;
int? _latestTick;
List<String> _selectedRowKeys = [];
int _rowsPerPage = 10;
#override
void initState() {
super.initState();
_sortColumnName = 'browser';
_sortAscending = false;
_timer = Timer.periodic(Duration(seconds: 1), (timer) {
if (!_willSearch) {
if (_latestTick != null && timer.tick > _latestTick!) {
_willSearch = true;
}
}
if (_willSearch) {
_willSearch = false;
_latestTick = null;
setState(() {
if (_filterTexts != null && _filterTexts!.isNotEmpty) {
_filterTexts = _filterTexts;
print('filterTexts = $_filterTexts');
}
});
}
});
}
#override
void dispose() {
super.dispose();
_timer?.cancel();
_timer = null;
}
#override
