Re: How to style specific cells in CellTable depending the value of that cell (GWT)?

From the javadoc of setCellStyleNames:

If you want to apply style names based on the row or cell value, override #getCellStyleNames(Context, Object) directly.

So:

IndexedColumn column3 = new IndexedColumn(2) {

  @Override

  public String getCellStyleNames(Cell.Context context, String, value) {

    if ("898".equals(value)) {

      return getView().getRes().css().myBoldColor();

    }

    return null;

  }

};

If the style depends on the indices rather than the actual value, then you can use RowStyles to apply a specific class to the line, setCellStyleNames to apply a specific class to the cells in the column, and then style the "intersection" of those:

.boldRow .boldColumn { font-weight: bold; }

(all cells in the 3 column would have class="boldColumn", but only the cells that also are in rows with class="boldRow" would actually be bold)

Ok, i have a CellTable that has 3 columns and 2 rows. I want the text in SOME specific cells (not all cell) in the table to be BOLD.

Please look at this code:

ListDataProvider<List<String>> dataProvider = new ListDataProvider<List<String>>();  dataProvider.addDataDisplay(table);  List<List<String>> list = dataProvider.getList();  List<String> sublist1= Arrays.asList("223","546","698");  List<String> sublist2= Arrays.asList("123","876","898");  List<String> sublist2= Arrays.asList("123","896","438");  IndexedColumn column1=new IndexedColumn(0);  table.addColumn(column1, "Col1");  IndexedColumn column2=new IndexedColumn(1);  table.addColumn(column2, "Col2");  IndexedColumn column3=new IndexedColumn(2);  table.addColumn(column3, "Col3");  

Now, I want the Cell that is the intersect of row2 & col3 (ie "898") to be BOLD, so if i do like this

column3.setCellStyleNames(getView().getRes().css().myBoldColor());  

Then it will make the whole column BOLD.

So, i think properly we need to loop over each cell in column3 & set the style accordingly, so that we can have the result like this:

Col1 - Col2 - Col3  223 - 546 - 698  123 - 876 - 898  123 - 896 - 438
