Data Table

The DataTable component is a versatile UI element used to display data in a tabular format, resembling a table. It efficiently iterates through a designated datasource, converting it into an organized list comprising rows and columns. In the DataTable, columns represent attributes, rows represent entities, and a header row labels the columns.

Use Cases

The DataTable component proves invaluable across a multitude of scenarios where data needs to be comprehensively displayed, including:

• Data Analysis: Utilize the DataTable to showcase datasets, enabling users to perform in-depth analysis, exploration, and comparison of various attributes.

• Inventory Management: Employ the DataTable in inventory management systems to present product details, quantities, and availability.

• Sales Reports: For tracking sales performance, the DataTable effectively displays revenue, product sales, and other relevant metrics.

Properties Customization

Enhance the DataTable component to align with your application's requirements using the following customization options:

• Header Height: Define the height of the header row in pixels.

• Row Height: Set the height of each row (excluding the header) in pixels.

• Columns Area: The columns area is where developers can manage the columns within the DataTable. It provides options for adding, moving, or removing columns to customize the structure of the table.

  • Adding Columns: To add a new column, click on the + icon. This action triggers the appearance of a new column configuration area located at the bottom of the column list. This area allows you to define properties for the new column:

    • Title: The title is the text displayed in the header row as the label for the column. It also appears as the column name in the properties area.
    
    
    • Source: The source attribute specifies the datasource for the column. Typically, it refers to an attribute whose value depends on each element of the DataTable's DataSource. This determines the content to be displayed in the column cells.
    
    
    • Format: The format property allows you to define how the data in the column should be displayed. It specifies the visual representation of the data, such as date formatting or decimal places.
    
    
    • Width: The width of the column can be customized. You have the option to define the width in pixels or as a percentage. The unit menu at the right side of the entry area lets you choose between PX (pixels) or % (percentage).
    
    
    • Sorting: The sorting selector enables users to interactively sort the column. When this selector is activated, users can click on the header area of the column to perform ascending or descending sorting at runtime.

    

  • Column Duplication: Duplicate existing columns to replicate configurations quickly by clicking on the icon.

  • Column Removal: Delete columns that no longer serve a purpose by clicking on the icon.

  • Moving Column: Arrange columns to your preferred position by clicking on the icon

Data Integration

The DataTable component is data-bound, meaning it relies on an external data source to populate its options. This allows the component to display and interact with data.

info

The datasource for the DataTable component can take the form of either an ORDA entity selection or an array.

Data Binding

To associate data with the DataTable component, follow these steps:

• Navigate to the Properties Panel: Access the Data Access category located within the Properties panel for the Data Table component.


• Define the Datasource: Specify the appropriate Datasource that contains the data you want to display within the DataTable. For instance, you can select an entity selection, such as the Packages dataclass.

tip

Alternatively, you can establish the connection by dragging and dropping the datasource onto the DataTable component.

Data Display

When it comes to displaying columns in the DataTable component, you have two options:

• Property Customization in the Columns Area: Modify column settings according to your preferences directly from the Columns Area.

• Attribute Drag-and-Drop: Alternatively, you can include columns by dragging and dropping attributes from the datasource onto the DataTable.

Server-Side Interaction

Enhance DataTable interactivity by binding functions to events like onheaderclick and oncellclick. These events respond to user actions and retrieve event-specific details using the webEvent command.

Common attributes for onheaderclick and oncellclick:

Attribute	Type	Description
caller	Text	Server-side reference of the DataTable component.
data	Object	The data object containing event-specific information.
eventType	Text	Type of event that has been triggered ("onheaderclick" or "oncellclick")

• onheaderclick: Triggered when a user clicks a column header. The data object attribute includes:

Attribute	Type	Description
index	Number	The index of the clicked column header (starting from 0).
name	Text	The datasource of the column.

• oncellclick: Triggered when a user clicks a cell in a row. The data object attribute includes:

Attribute	Type	Description
index	Number	The index of the clicked column header (starting from 0).
name	Text	The datasource of the column.
row	Number	The number of the clicked row.

Dynamic Attribute Display

The Data Table component can link its currently selected entity to a datasource in the Selected Element field. This feature allows the component to automatically display the attributes of the selected element whenever a new entity is chosen.

These attributes can be showcased in other configured components, such as a Text component, to display the corresponding attribute values.

User Experience Features

The DataTable component provides a range of user-friendly features:

• Column Sorting: Users can sort data by clicking column headers .

• Resizable Columns: Adjust column widths to fit content .

• Drag-and-Drop Column Movement: Rearrange columns with ease .

• Selectable/Tabbable Rows: Navigate and select rows using keyboard tabbing.
