The tabledisplay consists of two views. These are represented by the tabs Tables and Table Content. The Tablestab contains the names of the internal tables selected by the user and their current status in the form of ahistory for special tools . The Table Content Display:  If you double-click the name of an internal table, you will see the view TableContent, shown below. The display shows the name and the type of table selected, followed by the columnheadings and their contents. The columns that contain table keys are highlighted in blue script. You can alsodisplay the key definition by clicking on the key icon in the display.The table attributes specification depends on the table type and contents. For example, the entry Standard[1000x68(2056)] means the following:The table is defined as a standard internal table.The table has 1000 lines with 68 columns each, each line having a length of 2056 bytes.

There youcan rearrange, even delete, columns so as to display the table as you wish to see it.You can also choose attributes of object references and fields in nested data objects for display in theTable Content. Your layout applies to the current table as soon as you choose Apply. You can also savethe layout — see below in 'Other Services of the Table Tool.'Not pleased with your layout changes after all? Simply choose Reset Column Configuration from thecontext menu or tool Services button to return the table to its native layout. Special case — object attributes: The Reference Line in the Column Configuration window showswhich row from the internal table is displayed for configuration. This information can be important to you if you are working with a table that contains references, and you want to display attributes of the referencedobjects.Object references in a table may, of course, point to objects of different classes with different attributes.Layout changes that you make affect attributes by name. You may, therefore, need to work with differentReference Lines from the table to display all of the object attributes that you want to see.  Example You want to display all of the object attributes in column 'REF' of your table ITAB1.REF contains a reference in row 1 to an object of class C1 with attributes ATTR1 and ATTR2. In row 2, itcontains a reference to C2 with attributes ATTR1 and ATTR3.In the Column Configurator or directly with the context menu, you would display row 1 (ReferenceLine 1). You could then set up display of ATTR1 and ATTR2.Then you would mark row 2. In the Column Configurator (Reference Line 2) or context menu, youcould add display of ATTR3 from the object of class C2. Info column:  The Info column in the Configurator adds information about particular columns in a table.Most commonly, you will see the icon Insert Subcomponents, which indicates that object attributes or fieldsof a structure can be added to the display. You may also see 'problem' icons, if you type in the name of anon-existent field, or if an attribute that is to be shown does not exist in the referenced line.The Column Configurator functions are also available in the context menu of the Table Tool and in the The Table Tool: Work With Internal Tables in the ABAP Deb... of 705/10/2014 12:54
