In Yahoo mail, if you want to fetch the Date of the four row
(mail), use the following code

E.g: Using record and playback
msgbox Browser("Yahoo! Mail - amar_kothuru@yah").Page
("Yahoo! Mail - amar_kothuru@yah").WebTable
("Sender").GetCellData(4,9)

E.g.:Using Descriptive Programming
msgbox Browser("name:=Yahoo! Mail - 
amar_kothuru@yahoo.co.in").Page("title:=Yahoo! Mail - 
amar_kothuru@yahoo.co.in").WebTable
("name:=toggleAll").GetCellData(4,9)


Why you are not able to fetch the date value is

Sometimes QTP gives invalid column count of the webtable 
and if you follow the same, you can't able to fetch all 
column values.. So try different combinations of column 
numbers(more than actual columnCount) and get the results.

When you add Webtable object to object repository and it 
shows the column count as 7. I think, you tried upto the 
column number 7. But if you pass the column number as 9, 
you could get the date value. if pass column number as 10, 
you would get Size value.

Set oPageObject = Browser("browsername").Page
("pagename").Object
Set oTableObject = oPageObject.getElementsByTagName("table")

		 
		 sActualText = oTableObject
(inxexoftable).rows(3).cells(columnnumberofdate).innerText

inxexoftable = if page have multiple tables then the index 
should be the inbox table.

hope this will helps u.
