creating textcolumns inquiry

[Led Estonilo]

in GWT do we need to declare every column present on the table?

final DataGrid<DTO> table = new DataGrid<DTO>();
		
		TextColumn<DTO> firstValue= new TextColumn<DTO>() {
			@Override
			public String getValue(DTO object) {
				return a.getFistField();
			}
		};

		TextColumn<DTO> firstValue= new TextColumn<DTO>() {
			@Override
			public String getValue(DTO object) {
				return a.getSecondField();
			}
};
       
TextColumn<DTO> lastValue= new TextColumn<DTO>() {
			@Override
			public String getValue(DTO object) {
				return a.getNField();
			}
		};
            

can we just put it in a method to reduce redundant task?

how?

Sure you can. However you will need to figure out how to return the correct getValue(); because that value will be used as display.
And eventually you will need to add all the columns to the table. Check out the example here http://www.gwtproject.org/doc/latest/DevGuideUiCellTable.html
