Lets checkout how to apply different styles for cell, yes cell not the entire column. SALV object model does provide us the objects to achieve this.
Background
Today is kind of a SALV day – specifically SALV HOTSPOT day. Fellow developer has posted a question on ABAP Help Forums, Using HOTSPOTs. Similar type of question on HOTSPOT was also asked on the SDN Forum CL_SALV_TABLE set_cell_type_column. But both are using different methods of SALV model to achieve similar functionality.
As you have seen in past, in post SALV Table 8 – Add & Handle Hotspot on how to create the HOTSPOT on the single column. This task is being done by the method SET_CELL_TYPE of the Columns object CL_SALV_COLUMNS_TABLE. We also seen, how we can handle that using the events object of the SALV.
Design Time Consideration
To apply different styles like HOTSPOT, Button, etc on different cells, SALV model has the method SET_CELL_TYPE_COLUMN of the class CL_SALV_COLUMNS_TABLE. To be able to effectively use this method, you need to do this:
- Add a field with type SALV_T_INT4_COLUMN in the Output table. Here the output table is the table which we would use to generate the output in SALV.
- Populate the data in the table.
- Call method SET_CELL_TYPE_COLUMN, to set the name of the field of the style table which we have created in first step.
Since you have added the field in the output table itself, you can easily populate different styles for each row. If you specify the COLUMNNAME while populating the data in the style table, the style would be only applicable to that particular column for the row in which you are populating the styles.
Code Lines
Lets checkout the code lines. For this post, we’ll restrict till only applying different styles on the different cells. I’ll try to cover this in future post.

Good one!
Really good, its been very helpful for me..
Thanks
i want to check event for input field in such way that the when user input any one key suppose press ‘v’ then certain event or module get called.
purpose of my question is that i want to check the key event that when user press a character in mobile no. field then i can erase that character and user have to input only numeric field…..
