Hi ,
I want to add column Dynamically in Nattable.

suppose I ve table "tab1". It has two columns ,column1 and column2.

Table is populated with data.

Now how to add a new column dynamically/programatically to tab1 .

To populate data I am using the code like this:

for (int i = 0; i < tabsize; i++) {
myList.add(new MyTableRow(data1,data2));
}

where MyTableRow implements TableRow with two properties ,for each column.

Now If I add new column how I will be able to populate data .

Like SWT ,whetherer I can add data to each column ,without defining MyTableRow:

swtrowItem_1.setText(j,rdata);

Please suggest.

Hi Dirk,
Thanks for your reply.

DynamicColumn is working .

Now I have the following queries:
1. In "DynamicColumnExample" sample , when I click on newly added column for sorting,the widget hangs.

2. For adding EDIT rule for cell I ve added the following code:

ColumnOverrideLabelAccumulator labelAccumulator = new ColumnOverrideLabelAccumulator(bodyDataLayer);
bodyDataLayer.setConfigLabelAccumulator(labelAccumulator);

registerColumnLabels(labelAccumulator);

natTable.addConfiguration(new EditorConfiguration(columns)); //For EDIT Rule

public class EditorConfiguration extends AbstractRegistryConfiguration {

private ArrayList<String> columnLabel;

public EditorConfiguration(ArrayList<String> columnLabel)
{
this.columnLabel=columnLabel;
}

@Override
public void configureRegistry(IConfigRegistry configRegistry) {

for(int k=0;k<columnLabel.size();k++)
{

configRegistry.registerConfigAttribute(
EditConfigAttributes.CELL_EDITABLE_RULE,
IEditableRule.ALWAYS_EDITABLE,DisplayMode.EDIT,columnLabel.get(k));

registerSingleLineEditors(configRegistry,columnLabel.get(k));
}

}

But the Editor does not work . All the cell are disabled for Editing.

3. For Filter Row I ve added the following code:

private EventList values = GlazedLists.eventList(new ArrayList());

values.add(createValueRow("Homer"));
values.add(createValueRow("Marge"));
values.add(createValueRow("Bart"));
values.add(createValueRow("Lisa"));
values.add(createValueRow("Maggie"));

SortedList sortedRows = new SortedList(values, null);
filterList = new FilterList(sortedRows);

MyColumnPropertyAccessor columnPropertyAccessor=new MyColumnPropertyAccessor();
SimpleColumnHeaderDataProvider columnHeaderDataProvider =new SimpleColumnHeaderDataProvider();

final GlazedListsGridLayer glazedListsGridLayer = new GlazedListsGridLayer(
filterList,
columnPropertyAccessor,
columnHeaderDataProvider ,
configRegistry,
true);

....

glazedListsGridLayer.setColumnHeaderLayer(filterRowHeaderLayer);

But the Filter is not showing properly in Table

You need to register the configurations to your new columns after creation. As you register configurations against labels that correspond to your column, your new columns don't have the necessary configurations/labels.

Hi,
Thanks.
Now EDIT configuration is working .
1.But I am unable to add filterrow to this dynamic table( using GlazedListsGridLayer). 2.Filterrow should be updated when a new column is added i.e filter for newly added column should be shown
