Answer 1

Have alignment: Alignment.center inside Container,

Container(
         alignment: Alignment.center,
         padding: EdgeInsets.all(2.0),
         child: Text('G',
         style: TextStyle(fontWeight: FontWeight.bold)),
         ),

This is an example and a part of your code ! Table children:

children: <TableRow>[
                  TableRow(
                    children: <Widget>[
                    Container(
                      padding: EdgeInsets.all(2.0),
                      child: Text('G',
                          style: TextStyle(fontWeight: FontWeight.bold),
                                 textAlign:TextAlign.center),
                    ),
                    Container(
                      padding: EdgeInsets.all(2.0),
                      child: Text('A',
                          style: TextStyle(fontWeight: FontWeight.bold),
                                 textAlign:TextAlign.center),
                    ),
                    Container(
                      padding: EdgeInsets.all(2.0),
                      child: Text('P',
                          style: TextStyle(fontWeight: FontWeight.bold),
                                 textAlign:TextAlign.center),
                    ),
                    Container(
