From my understanding it is.
hmmm...
as we had the same issue a few weeks ago, I compared the NatTable behavior to Excel behavior.
While Excel can decide, whether a column is fully selected or all data rows are selected, NatTable cannot. It's quiet irritating, when you use a NatGridLayerPainter with full row selection and having a few rows only, so the NatTable gets "filled" with empty rows.
If you select all rows, there are still the empty rows, rendered by NatGridLayerPainter, that are not selected. But when you change a single column width, NatTable changes all the available columns to the same width, as all available data rows are selected 
When selecting all data rows in Excel - leaving the empty rows unselected - and changing a single column, only the single column will resize.

That behavior is implemented in SelectionLayer#handleColumnResizeCommand(ColumnResizeCommand). If you expect a different behavior feel free to extend SelectionLayer and do whatever you expect that should happen.
We solved this by simply delegating the ColumnResizeCommand to the underlying layer in our own SelectionLayer implementation.
@Override
protected boolean handleColumnResizeCommand (ColumnResizeCommand pCommand)
{
return underlyingLayer.doCommand (pCommand);
}
