I've constructed a Nattable, I want to give the coloring capability something similar to excel. And I want to store and retrive it.

1) I have provided the ColorDialog, And got the RGB got selected.

2) For columns I have provided the register column override to provide the color. (Its working fine).

3) Using ColumnOverrideLabelAccumulator I'm setting the color for the Row and cells.

And I'm setting the DefaultNatTableStyleConfiguration, with the new registry configuration.

Then I configure the Nattable and redrawing the Nattable. The latest color state is not getting applied to the cells.

Whats is the way to redraw the Nattable.

And what is the method you are suggesting to store the color configuration for future reference.

Look at the Classic Examples - Styling - Styled Grid example as a reference. There you can use the styling dialog from the column header menu. The DisplayColumnStyleEditorCommandHandler is a persistable, so there you can get an idea about how to store such configurations for future use. Basically we have a StylePersistor class for that purpose.

I can't tell why your style configurations are not applied. Maybe an issue with your label accumulator or you are doing something wrong with the configuration. Add the DebugMenuConfiguration to be able to check on the rendered NatTable if the labels are correctly applied.

natTable.addConfiguration(new DebugMenuConfiguration(natTable);

With that configuration applied you can right click on a body cell and select the "Debug info" menu entry, which will open a dialog with some information on the selected cell. There are several examples that include that.

Thanks for the support.
with following modifications and its working fine.

1) DefaultNatTableStyleConfiguration - Register config attributes for the new color.

configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_STYLE,custStyle, DisplayMode.NORMAL, colorName);

2) Recreated ColumnOverrideLabelAccumulator with the new color values.

3) DataLayer.registerPersistable(columnLabelAccumulator);
