Hello all,
I have developed a table control using wizard.
Now i need to add two additional columns into the existing table control.
Can it be done and if yes kindly help with the solution.

Hi
Go through the below steps
1) Screen tables
A table can be created in transaction. These tables, when designed on the screen are called as SCREEN TABLES.
These are of two types.
Table Controls and Step loops
These tables are treated as Loops.
2)Features of Table Controls
Data is displayed in the form of table.
Table control gives user the feeling of an actual table.
You can scroll through the table vertically as well as horizontally.
You can select rows and columns.
You can resize the with of columns.
You can have separator lines between rows and columns.
Automatic resizing of the table when the user resizes the window.
You can update information in the table control and it can be updated in the database table by writing code for it.
3)Steps for creating table control
Declaration of table control in module pool program.
Designing of table controls on the screen.
Passing data to table control in flow logic.
4)Declaration of TC in MPP
syntax:
controls <name of table control> type tableview using screen <escreen no.f>.
5)Designing Table control on screen
Click on Table in Control bar and place it on the screen. You can adjust the length and width of the Table Control.
Name the table control.(same name as given in data declaration).
From dictionary object OR from program fields select the fields and place them in the table control
6)Passing data to table control
Usually transfer of data from program to screen is automatic.
In case of TC, you need to explicitly transfer the data to table control.
ABAP/4 provides Loop statement, which is associated with flow logic to transfer the data.
7)Passing of data contd.
PBO.
Loop at <name of internal table> with control <name of table control> cursor <scroll variable>.
modulecc.
Endloop.
PAI.
Loop at < name of internal table>.Endloop.
8)Scroll variables
Top_line : the row of table where the screen display starts.
Current_line : the row currently being processed inside a loop.
9)Transfer of data from prg to TC.
With eLoop at cf statement, the first row is placed in the header of internal table.
If any module is specified between Loop and End loop, it will be executed. In this module, generally we will be assigning this internal table fields to table control screen fields.
The row in internal table is transferred to the TC as stated in the eLoop atc..f statement.
The system encounters the eEndloopf statement and control is passed back to the next line of internal table.
In the same way all the records of the internal table are passed to the TC.
