hi guys,

I have created a TableViewer, now it can add and delete rows dynamically using context menu, but how to add a new column? when add the new column, we can set the default column header text, is there a way to edit this column header like cellEditor? can someone give me some sample code for this?

thanks,
Ping

Hi Ping Luo,

i think you can simple create a new Column with:

TreeViewerColumn viewerColumn = new TreeViewerColumn( myTreeViewer, SWT.NONE );

Maybe you have to call this afterwards to make the changes visible

tree.layout()

Afterwards you can call:

 column.setText( columnTitle );

to set the header text. A CellEditor is not possible for a column header, maybe you provide an extra dialog with textfields where you can rename the column headers.

Maybe it would be nice for you to have a dialog where you can select which columns should be visible, define the headers and maybe the width. In addition you can save the configuration, and load it on startup.
