we don't have provision to set position of column we do it in ALV by using set_position
As Kiran suggested, you need to delete the existing columns and add the columns as per your requirement by using the parameter INDEX in method ADD_COLUMN / ADD_GROUPED_COLUMN
To get all columns use GET_COLUMNS / GET_GROUPED_COLUMNS
To delete columns use REMOVE_COLUMN(S) / REMOVE_GROUPED_COLUMN(S)
There is no method(s) to set the column position in table. However, you have to dynamically remove/add using remove_column( ) and add_column( ) by passing index to it in wddomodifyview( ) method dynamically.
Can we rearrange the existing columns of nodes by passing the index and column name.
Unfortunately, No! you have to remove the column and add it.
As I have already have a component with table need to rearrange the columns.
Is it a standard component or custom component?
If it is a custom component, you can rearrange by right click on column and move up/down.
If it is a standard component, consider deleting the table( Remove Element) in enhancement mode and then create a new Table UI with specified order. Or, create a post exit in wddomodifyview and then get the table reference and use remove_column( ) add_column( ) methods
code snippet:
DATA: lr_table TYPE REF TO cl_wd_table,
lr_abs_col TYPE REF TO cl_wd_abstr_table_column,
lr_col TYPE REF TO cl_wd_table_column.
IF first_time EQ abap_true.
* get table reference
lr_table ?= view->get_element( id = 'TABLE ). " ID of Table UI
