How to customize the last row of a CellTable in GWT?


Assume each row has the format:

Data   | <Delete Button>

Now I am trying to add an empty row at the end. And I would like to not showing the <Delete Button> at the last row. I added the empty data through data provider. Is there a way to achieve this?


Solution

  • There is a method you can override when you create a column:

    Column<MyObject, Number> myColumn = new Column<MyObject, Number>(new NumberCell()) {
    
        @Override
        public String getCellStyleNames(Context context, MyObject myObject) {
            return context.getIndex() == displayItems.size() - 1 ? "hide" : null;
        }  
    };
    

    context.getIndex() gives you a row number. You can define a CSS style in your CSS file like "hide" with a rule "opacity: 0" or "display: none", and return this style only for the last row.

    My example is NumberCell, but it applies to all cells.
