Defining Column Width 

Use

You are able to change the width of the columns in the ALV output in different ways. Here you differentiate between columns in the content of the ALV output (represented by a COLUMN object) and other types of columns (such as hierarchy column of the tree structure, column in design object).

Features

You are able to make the following settings for column width:

·        Set output width of a column (COLUMN object)

·        Set width of hierarchy column in the tree structure

·        Change width of a column in table-type layout of a design object

·        Adapt width to space needed for the values

·        Hide column completely (section called Settings Visibility of a Column)

Set Output Width

You are able to set the width of a column in the content of the ALV output no matter how large the field has been defined for the internal data table.

Set Width of Hierarchy Column

You are able to choose whether you want to specify the width of the hierarchy column in the tree structure in pixels or in characters.

Width of a Column in Table-Type Layout of a Design Object

If you use a table-type layout in a design object, you control the width of the column using its contents: the longer the text in a cell, the wider the column.

Adapt Width to Space Required by Values

You are able to automatically set the width of columns so that all values are displayed completely by optimizing the column. You can make this setting for each column individually or for all columns simultaneously.

Display type ALV Tool	Classic ABAP list	Full screen	In the Container
Simple, two-dimensional table	Yes	Yes	Yes
Hierarchical-sequential list	Yes
Tree structure		Yes	Yes

Methods

Function	Class	Method
Optimize individual column	CL_SALV_COLUMN	SET_OPTIMIZED
Check whether a column is optimized		IS_OPTIMIZED
Optimize all columns simultaneously	CL_SALV_COLUMNS	SET_OPTIMIZE
Check whether all columns are optimized		IS_OPTIMIZED

In the printout, the columns that are output are exactly as wide as they are on the screen by default. In the full-screen display of a simple, two-dimensional table, you are able to determine that the column widths be optimized in the printout. To do this, use the method SET_COLUMN_OPTIMIZATION in the CL_SALV_PRINT class. With the IS_COLUMN_OPTIMIZATION you check whether the columns are optimized in the printout.
