You can replace those text widget that you want to make editable with TextField. First define TextEditingController with default value like this:

TextEditingController priceOneController = TextEditingController(text: '5.5');
TextEditingController priceTwoController = TextEditingController(text: '6.9');

then use them like this:

TableRow(
    children: [
      Container(
        padding: EdgeInsets.only(top: 15),
        height: 50,
        color: Colors.cyan,
        child: Column(children: [
          Text(
             'Price',
              style: TextStyle(fontSize: 20),
          )
        ]),
      ),
      TableCell(
        verticalAlignment: TableCellVerticalAlignment.fill,
        child: Container(
          padding: EdgeInsets.only(top: 15),
          color: Colors.white,
          child: Column(children: [
            TextField(
               controller: priceOneController,
               InputDecoration(border: InputBorder.none),
               style:  TextStyle(fontSize: 20),
            ),
          ]),
        ),
      ),
      Container(
        padding: EdgeInsets.only(top: 15),
        height: 50,
        color: Colors.white,
        child: Column(children: [
          TextField(
             controller: priceTwoController,
             InputDecoration(border: InputBorder.none),
             style:  TextStyle(fontSize: 20),
          ),
        ]),
      ),
    ],
  ),
