Through the thread QlikSense-Increasing the No. of columns in Table I got solution for problem 1. Take away is in QS 1.0.2 we can't change the column width of a Table.
Still waiting experts to help me on second issue
I used date#() to read dates from source CSV file.
Full code is here:
IF (match(LEFT(Subject,3),'RE:', 'Re:', 're:','rE:'),MID(Subject,4),Subject)
DATE (alt( date#("Date Sent",'M/D/YYYY HH:MM'),date#("Date Sent",'m/d/yyyy h:mm')),'MM/DD/YYYY h:mm') as [Sent on],
date#("Date Received", 'm/d/yyyy h:mm') as [Date Received],
(txt, codepage is 1252, embedded labels, delimiter is ',', msq) ;
RIGHT JOIN ([MIN_INBOX])
Date(min([Sent on]),'MM/DD/YYYY HH:MM') as [First Time Replied]
DROP TABLES [Sentbox];
