Manipulation of Table Control

Introduction

A table control is an area on the screen in which the system displays data in tabular form. It is

processed using a loop.

Benefits of using a table control are

Resizable table for displaying and editing data.

The user or program can change the column width and position, save the

changes, and reload them later.

Check column for marking lines; marked lines are highlighted in a different color.

Line selection: single lines, multiple lines, all lines, and deselection.

Column headings double as pushbuttons for marking columns.

Scrollbars for horizontal and vertical scrolling.

Any number of key (leading) columns can be set.
