The easiest thing you can do is to wrap the content of each table cell with a Padding like so:
TableRow (children: [
TableCell(
child:Padding(
padding: const EdgeInsets.all(8.0),
child: Text(EMAIL,
style: TextStyle(
fontWeight: FontWeight.bold,
),),
),
),
TableCell(
child:Padding(
padding: const EdgeInsets.all(8.0),
child: Text(authUser.email),
)
),
])
You could wrap your table with Padding widget like this:
Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Table(
children: [
TableRow(
children: [
Text('1'),
Text('2'),
Text('3'),
],
),
],
),
),
