Typically by adding the header menu configuration that enables the column header menu with entries for column hide/show.

Or by executing the corresponding commands on the NatTable instance.

Lets Say i have 4 out of 10 are hidden by default.

Now i have some mechanism select and deselect the column visibility using the Header manu contribution.

If have to hide the another two column what i have to do?

columnHideShowLayer.hideColumnPositions(hiddenColumnIndecies) works only for the first time.

Dznamically if i change the column configuration how to hide or show the column

the above code does not work in that case.

Question> What should be done to hide/show the column dynamically?

What do you mean with dynamically?

You shouldn't call columnHideShowLayer.hideColumnPositions() directly, but execute the ColumnHideCommand on the NatTable. This operates on the visible column positions and translates it correctly when it is transported down the layer stack.

At the moment this solve the problem,

columnHideShowLayer.showAllColumns();
columnHideShowLayer.hideColumnPositions(hiddenColumnIndecies);
natTable.update();

ColumnShowHideCommand accepts Only index that means i have to loop through and excecute it in order to hide mutiple column?

How do i find the visible column position.

In my case whenever i change preference where i configure my columns it has to be be applied to the table in preference listener and dont have any nattable event.
