Widget "Table" can be used to display arrays.

In practice, it is also often used to display large amounts of data such as logbook entries or a list of measured values. Many HMI applications, however, take a relatively long time to display the table at runtime.

This is usually caused by binding a large amount of data to the table. There have been examples where 10,000 elements have been bound. This means, however, that these 10,000 elements must be transferred to the browser as well as that each table cell behaves like a widget.

In other words, a table with 1000 data points in the background needs almost as much computing time as a single page with 1000 widgets.

Optimizing tables

On clients such as the T30/T50, using tables with a very large number of data points should be avoided. If a large amount of data must be displayed, it is recommended to only bind the amount of data that can actually be displayed based on the size of widget "Table".

The remaining data can be copied over using an application program if necessary. Paging up and down in the list can be done using "Button" widgets, for example.
