Principle of working - Table.

Tabel is intended to view and write data in a tabel form: single and hierarchical.

There are two modes in use: reading and writing mode. In reading mode you can only read data, but in writing mode you can read and write data.

Usable fields:

• Column header - To show column titles. Location is uppermost row.
• Column footer - To show column summary data. Location is lowermost row.
• Row indicator - To show active row. Small arrow in front of the row. In writing mode it changes into pencil.
• Horizontal scroll bar - To scroll rows in table horizontally (left and right).
• Vertical scroll bar - To scroll rows in table vertically (up and down).
• Column sorting - To show column sorting. Small arrow on the right side of the column. Arrow down indicates that data is sorted decreasingly and arrow up indicates that data is sorted increasingly.
• Hierarchical table - To show data hierarchically. Small box with symbol '+' or '-' in front of the row. Symbol '+' indicates that inner table is closed and symbol '-' indicates that inner table is opened.
• Selection window - To open selection window. Small button in specific field. Usable only in writing mode.

Usage when reading:

• Column sorting - To activate column sorting, click on the column name you want to sort data by. To deactivate column sorting, hold down key 'Ctrl' and click on the column name you want to unsort. To sort data by multiple columns, hold down key 'Ctrl' and click on columns you want to sort data by.
• Hiararchical table - To open inner table, click the box with symbol '+' in front of the row and to close inner table, click the box with symbol '-'. To show only inner table, click on small magnifying-glass in upper right corner of the inner table. To restore to standard hierarchical view, click on small cross in upper right corner of the inner table.
• Movement - For movement you can use mouse or arrow keys.

Usage when writing:

• Add/edit row - In writing mode you can move forward and confirm written data in field with key 'Enter'. If row is being written, then row change with arrow keys or with mouse is impossible. To restore row data, press key 'Esc'. One key press restores rows single active field data, two presses restores entire row data. To save row data, you must confirm all writable fields (it means that row is saved whan last writable field is confirmed).
