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.

Not sure about the spec you are referring to?
I see https://docs.oracle.com/en/java/javase/22/docs/api/java.desktop/javax/swing/JTable.html#AUTO_RESIZE_NEXT_COLUMN
`When a column is adjusted in the UI, adjust the next column the opposite way.`

It seems to behave similarly with and without the fix, although it may not be what the spec is demanding..It is not similar to LAST_COLUMN spec so cannot be handled along with it..I guess it's a separate issue, if it is one...
