There may be a situation where we need to modify the Column Title display string.
We can change the Column title using the Display string in the Format Field option.

Select the Column Title in the Cross-tab. Right click and select Format Field option. Under the Common Tab select the Display string x-2 button.

Use the GridRowColumnValue function in the condition statement
i.e.
if GridRowColumnValue(“TableName.ColumnName”)=”string to Check” then
“New Disp String”
Else if GridRowColumnValue(“TableName.ColumnName”)=”string to Check” then
“New Disp String2″
