Explain Table Controls ?

Answer

Table controls and step loops are objects for screen table display that you add to a screen in the Screen Painter.

From a programming standpoint, table controls and step loops are almost exactly the same. Table controls are simply improved step loops that display data with the look and feel associated with tables in desktop applications.

With table controls, the user can:

• Scroll through the table vertically and horizontally
• Re-size the width of a column
• Scroll within a field (when field contents are wider than the field)
• Select table rows or columns
• Re-order the sequence of columns
• Save the current display settings for future use

Table controls also offer special formatting features (some automatic, some optional) that make tables easier to look at and use. Table Control provides -

• automatic table resizing (vertical and horizontal) when the user resizes the window
• separator lines between rows and between columns (vertical and horizontal)
• column header fields for all columns

One feature of step loops is that their table rows can span more than one line on the screen. A row of a table control, on the other hand, must always be contained in a single line (although scrolling is possible).

In general, many of the features provided by the table control are handled locally by your system's SAPgui frontend, so you do not need to program them yourself. The only notable exception to this is vertical scrolling.
