If the user set the mode to `AUTO_RESIZE_NEXT_COLUMN`, all columns are of same width and resized on expanding of container window. As per the spec ( `AUTO_RESIZE_NEXT_COLUMN: Use just the column after the resizing column. This results in the "boundary" or divider between adjacent cells being independently adjustable.`) only the next column should be resized not all the columns. Is it the correct behavior ? If not, shouldn't `AUTO_RESIZE_NEXT_COLUMN` also needs to be handle along with `AUTO_RESIZE_LAST_COLUMN` ? **or** user implementation needs to be changed to handle this mode ? _Otherwise current fix is working as expected for `AUTO_RESIZE_LAST_COLUMN`._ ------------- PR Comment: https://git.openjdk.org/jdk/pull/20107#issuecomment-2227988188
