I tried to do this:
lr_column = wd_this->alv_my_table_config->if_salv_wd_column_settings~get_column( 'COMMENTS' ).
lr_column->SET_WIDTH( '8px' ).
lr_column->SET_RESIZABLE( abap_false ).
This doesn't work and the column "COMMENTS" keeps resizing according to the length of the longest comment
I want to restrict the number of visible characters without wrapping or anything.
Basically I want to keep the cell dimensions always the same but still be able to write long comments.
