Widget Core Function

The Table Widget is very versatile and acts as a kind of container for sub-widgets. It can include Input, Computed, Lookup, Hidden, or LinkRow column types. You can create tables by:
  • Computing each column
  • Asking the user for data entry or data selection
  • Setting labels and text outputs
The table widget is similar to Excel tables - you can have cells for data entry, formulas, dropdowns, etc. The key difference is that you create different modes of “column” creation rather than individual “cell” creation.

​
UI Experience

Interactive

Users can input data, expand rows, and interact with different column types

Informational

Display computed results and organized data in tabular format

​
Data Organization and Manipulation

  • Primary widget for creating tables
  • Each column can be set as a sub-widget
  • Sub-widgets have most but not all capabilities of standalone widgets

Cell Checks

To add cell checks, use JSON form in the cellCheck field: 
[
  {
    "result": "",
    "condition": ""
  }
]

​
Example Cell Check

This example from the cfsSteelMemberAS4600-2018 template adds a cell check in the third cell where users can only input negative values for negative moment: Cell Check Example

Example Code

{
  "type": "sheetTemplateWidgets",
  "attributes": {
    "type": "table",
    "referenceId": "",
    "label": "",
    "symbol": "",
    "expand": false,
    "tableLength": "",
    "defaultValue": [],
    "visibleIf": "",
    "export": false,
    "dataColumns": [],
    "references": "",
    "description": "",
    "authorNotes": ""
  }
}

​
Parameters

​
type
string
required
Must be “table” - defines the widget type
​
label
string
required
The name of the widget
​
symbol
string (KaTeX)
required
Symbol for the widget displayed in KaTeX format
​
expand
boolean
default:"false"
required
Whether the table will be expandable by user input. At least one column must be "type": "input", and this may NOT be true if tableLength is defined
​
tableLength
string (equation)
An equation that must resolve to an integer, defining the number of rows to display. Most useful if your table has all "type": "computed" columns
​
defaultValue
matrix
Array of default values for initial display in the table
​
visibleIf
string (equation)
default:"true"
An equation that must result in true/false and can hide the widget if certain conditions are met. If visibleIf==false, any fields referencing this table will error
​
export
boolean
default:"false"
Whether to export the widget value for use elsewhere in the platform, such as in load linking
​
dataColumns
Table Column Object
required
Defines all columns in the table, which may consist of several types of columns
​
referenceId
string
required
Unique reference ID of the widget
​
description
string
Description of the table (not currently displayed, but will be)
​
references
string
required
Relevant code or standard reference for the table
​
authorNotes
string
Internal development notes; never displayed publicly
​
referenceImage
string (image dataURI)
Any image specifically relevant to the widget

Important Notes

The table widget resolves to a matrix of values that can be subset, mutated, or exported for various computations.

Best Practices

  • Use appropriate column types for your data needs
  • Consider using tableLength for computed-only tables
  • Implement cell checks to validate user input
  • Use expand functionality when users need to add variable numbers of entries
  • Always provide meaningful labels and references
