title	Description

The power table is a more customizable version of the table component, and it comes with advanced features such as drag-and-drop rows, multi-column sorting, column filtering, and cell-spanning. Customization comes through extensive use of extension functions, which are available to configure how each cell of the table looks, how the headers look, etc.

Basic Usage

The basics are just like the classic table - you simply bind the table's "data" property to your data, most often by using a SQL query binding. Note that many of the options built into the classic table have been moved to extension functions in the power table.

Power Table Features

Multi-column sorting. To sort multiple columns, select the header of the first column, hold down the Control key, then select the header of the next column. Click on the header again to reverse the sort order, and click a third time to remove sorting on the column.
Column filtering. Columns can be temporarily hidden from view using column filtering. Right-click on the header of the table, and uncheck columns that you would like to hide. You can disable this feature by disabling the Column Chooser Menu property on the table.
Column reordering. You can switch the locations of columns on the table using column reordering. Drag the header of the column that you would like to move to a new location on the table. You can disable this feature by disabling the Columns Re-Orderable property on the table.
Cell spanning. A cell can be spanned across multiple columns and rows. Keep in mind that you must explicitly define the locations of cells that must be spanned. This means that if you would like to use cell spanning, any other table features that change how the table is displayed will be disabled automatically (such as sorting, column filtering and column reordering). Click on the Cell Span Data dataset to configure spanning. Within the dataset, add a row for each new span. The "row" column controls the row in the table where the span will start. The "column" column controls the column where the span will start. The "width" column controls how many columns the span will cover. The "height" column controls how many rows the span will cover. Adding a row where "row=4, column=1, width=2, height=3" results in a span starting on the fifth row of the table and the second column (using 0-based indexing). The span will cover the second and third columns in the row and will also cover two rows below the fifth row, as shown below.
Drag and Drop. This feature allows you to drag rows from one power table to another power table. In order to perform drag and drop, you must implement the onRowsDropped() extension function on the destination table. This is so that you can adapt the data from one table to the other within the function. You must also enable the Row Dragging Enabled property on both tables.
Row Copying. This feature allows you to select rows and copy them to the clipboard using the standard keyboard shortcut Ctrl + C. These can then be pasted anywhere, even outside of Ignition.

Note
Even if a column is set to be editable, the edit must be handled by the onCellEdited extension function. If that extension function is not enabled and properly set up, the cell will revert back to its previous value.

title	onCellEdited

Description

Called when the user has edited a cell in the table. It is up to the implementation of this function to alter the underlying data that drives the table. This might mean altering the dataset directly, or running a SQL UPDATE query to update data in the database.

Note

If the script on this extension function causes the Power Table to lose focus, the cell commit will occur twice. For example, if system.gui.confirm() is called, then two confirmation boxes will appear. In cases where the script will cause the focus to switch between multiple objects, the script should be placed in a function, and wrapped in a call to system.util.invokeLater()

Code Block

	def myFunction():
		"""		
		Do your work here
		"""
		system.gui.messageBox("Assuming you don't change focus outside of this script\nYou will only see this message once per cell edit")
	system.util.invokeLater(myFunction)

Parameters

Component self - A reference to the component that is invoking this function.

int rowIndex - Index of the row that was edited, relative to the underlying dataset.

int colIndex - Index of the column that was edited, relative to the underlying dataset.

string colName - Name of the column in the underlying dataset.

Object oldValue - The old value at the location, before it was edited.

This component has a table customizer that allows customization of the individual columns including hiding columns, enabling editing, changing format, etc. It is important to note that when editing cells directly in the Power Table, it doesn't modify the underlying dataset. You can use the onCellEdited extension function and uncomment the sample code to make table edits change the underlying Dataset, or even the original source of data (ie: if using a SQL Query).
