Table Control (SAP Library - Web Dynpro for ABAP)

Table Control

Integration

The Table Control screen element is mapped onto the Web Dynpro UI element Table, which contains a set of TableColumn elements. The TableColumn consists of a caption for the column header and a Web Dynpro UI element that was obtained by transforming a non-container screen element.

Table Control Mapping Rules

Table Property	Bound to Context	Value
AccessibilityDescription		INITIAL
DataSource	Node TABLE_DATA	The data for the cells in the table control
Design		Constant Standard
Enabled		Constant True
FirstVisibleRow	Attribute TC_TOP_LINE (default 0)	First visible line in table control
FirstActualRow	Attribute TC_TOP_LINE (default 0)	First visible line in table control
FooterVisible	Attribute FOOTER_VISIBLE	If true, the table footer with the paging arrows is visible.
ReadOnly		Constant False
RowCount		Constant -1
SelectionMode		Constant None Note: The selection mode for the table control (Selectability attribute for rows) is mapped by inserting a special DynproTableColumn that contains checkboxes with ID MARK for the selection markers.
Tooltip		INITIAL
Visible	Attribute VISIBLE (default visible/2)	Element runtime attribute Active
VisibleRowCount	Attribute TC_LINES	Number of visible lines in the table control. Set at runtime using the LINES attribute of the table control structure.
Width		INITIAL

TableColumn Mapping Rules

TableColumn Property	Bound to Context Attribute	Value
Design		Constant Standard
FilterValue		INITIAL
HAlign		Constant Auto
Resizable		Constant True
Selected	COLUMN_SELECTED	True, if the column for table control is selected. Set at runtime using the SELECTED attribute of the COLS table, which is part of the table control structure.
Visible	COLUMN_VISIBLE	True, if the column is to be visible. Set at runtime using the VISIBLE attribute of the COLS table, which is part of the table control structure.
Width	WIDTH	Width of the column (in character grids). Set at runtime using the SCREEN_LENGTH attribute of the COLS table, which is part of the table control structure.

Context Structure

This graphic is explained in the accompanying text

Context Structure of the Table

The context node for a table control (marked with 1 in the figure above) contains the following elements:

· A node with cardinality 0:n for the table data (2 in above image), which is used as the data source for the Table UI element.

· The subnodes of the table data node (3 in above figure) contain the data for the table cells. The structure of these nodes is element-specific and corresponds to the context structure of the non-container screen elements. If a row selection attribute is set, a node with the name of the corresponding ABAP variable is created. It stores the data for the selection column.

· Nodes for the table columns (4 in above figure). These nodes contain the context attributes used for binding TableColumn properties as described above.
