Formatting a dynamic datatable

Question

Hello, I am displaying a datatable on screen with a dynamic number of columns and rows and everything is working fine. However, I would also like to apply columnClass formatting to the columns and obviously the number of classes is dependent on the number of columns. In a regular static datatable in our system, I would normally do something like:
columnClasses="tierNameStyle,tierCheckStyle,tierNameStyle,tierNameStyle" styleClass="dataTableStyle"But if I add this into my dynamic datatable JSP as this, it ignores the formatting:
<h:dataTable binding = "#{dataSetBB.dataSetTableHeadings}" var="rows" value="#{dataSetBB.tableHeadingRows}" columnClasses="tierNameStyle,tierCheckStyle,tierNameStyle,tierNameStyle" styleClass="dataTableStyle"/>Is there a way to do this in the backing bean since I am doing everything else for the dynamic table there?

Answer 1

OK, I tried that and it still seems to be ignoring my columnClasses. Here is my code from the backing bean where I am building the table. Am I doing something wrong?:
     public DataSetBB(){
               //setup dataModel
               String[] colHeadings = new String[]{"Heading1", "Heading2", "Heading3"};
               String[] colDetail = new String[]{"Detail1", "Detail2", "Detail3"};
               Object[] headingsArray = new Object[]{colHeadings};
               Object[] detailArray = new Object[]{colDetail};
               tableHeadingRows = new ArrayDataModel();
               tableHeadingRows.setWrappedData(headingsArray);
               tableDetailRows = new ArrayDataModel();
               tableDetailRows.setWrappedData(detailArray);
               //setupTable
               dataSetTableHeadings = new HtmlDataTable();
               dataSetTableDetails = new HtmlDataTable();
               dataSetTableHeadings.setStyleClass("dataTableStyle");
               dataSetTableHeadings.setColumnClasses("tierNameStyle,tierCheckStyle,tierNameStyle");
               dataSetTableDetails.setStyleClass("dataTableStyle");
               dataSetTableDetails.setColumnClasses("tierNameStyle,tierCheckStyle,tierNameStyle");
               UIColumn col;
               UIInput in = null;
               Application app  = FacesContext.getCurrentInstance().getApplication();
               int colCount = colHeadings.length;
               for(int j = 0; j < colCount; ++j) {
                    in = new UIInput();
                    col = new UIColumn();
                    in.setId("input" + j);
                    ValueBinding vb = app.createValueBinding("#{rows["+j+"]}");
                    in.setValueBinding("value", vb);
                    in.setRendererType("javax.faces.Text");
                    col.getChildren().add(in);
                    dataSetTableHeadings.getChildren().add(col);
               for(int j = 0; j < colCount; ++j) {
                    in = new UIInput();
                    col = new UIColumn();
                    in.setId("detail" + j);
                    ValueBinding vb = app.createValueBinding("#{rows["+j+"]}");
                    in.setValueBinding("value", vb);
                    in.setRendererType("javax.faces.Text");
                    col.getChildren().add(in);
                    dataSetTableDetails.getChildren().add(col);
     }
