QTP is not identifying table with column names property but its identifing with index

[Anuradha B]

I am using descriptive programming. To identify table, using table property 'column names' with value ending with reg exp ("Ex: OrdNo.*) but QTP is not identifying any table which has reg exp value. Please find the below code

Code:

Browser("name:=Browser name","creationtime:=0").Page("title:=Page name").Webtable("column names:=Reference No.*","cols:=4")

But QTP identifies with index value

Code:

Browser("name:=Browser name","creationtime:=0").Page("title:=Page name").Webtable("Index:=34","cols:=4")

I can't change the column name with index because in others machine it is working fine.

Recently i have downgraded from IE9 to IE8, thinking this might be causing the problem but not sure.

Please any one suggest solution for this issue.
