A table is data structure that can be represented in a TablePage or a TableField.

• implements: ITable
• extends: AbstractTable

Description

Table can contains a set of structured data: the structure of the entity is defined by the columns. Each entity contained in the table is a row. At the intersection of a column and a row is a Cell. A Cell describes how the value is represented (displayed text, colors, style, icon...).

Example

magine the you want to represent Persons that are structured as followed:

• Name (String)
• First name (String)
• Age (Integer)
• Date of birth (Date)

A such table needs to contains 4 columns :

• NameColumn a String Column
• FirstNameColumn a String Column
• AgeColumn a Integer Column
• BirthColumn a Date Column

TODO
Add a Diagram to represent this table

Access to the data

To access a value of a table, the common pattern is to go throw the column. For example if you want to access the age of a person, at a precise row index r, the code is:

  private Integer getAgeOfPersonAtRow(int r){
    return getTable().getAgeColumn().getValue(r);
  }
