Changing column width in Inbox

I use Flag, From, Subject, Received.
The column for Subject is too wide and the column for Received is
ahowing at the far right edge of the screen. How can I adjust the width of these columns?

Not sure if this is what you want, but if you place the mouse at the beginning of the column (on the column line), you will notice it changes to <__> (less than+dash+greater than). You could then move the column left or right.

Sorry for the ‘choppy’ explanation…

I have tried using the technique you described and it will not let me change the last column that contains “Received”
I can adjust other couumns but not this one

I need to give this some more thought…
