Table<T>

A custom table web component for BIM applications. HTML tag: bim-table

Extends

• LitElement

Type parameters

Type parameter	Value
T extends TableRowData	TableRowData

Properties

dataTransform

dataTransform: TableDataTransform<T> = {}

A property representing the rules for transforming table data. The keys of the object are the column names, and the values are functions that define the transformation logic.

Default Value

An empty object.

---

expanded

expanded: boolean = false

A boolean property that determines whether the table is expanded or not. When true, the table will be expanded to show all rows. When false, the table will be collapsed to show only the top-level rows.

Default Value

false

Examples

table.expanded = true;

<bim-table expanded></bim-table>

---

filterFunction()?

optional filterFunction: (queryString, data) => boolean

A function type representing the filter function for the table. This function is used to determine whether a given row of data should be included in the filtered results.

Parameters

Parameter	Type	Description
queryString	string	The search string used to filter the data.
data	TableGroupData<T>	The data row to be filtered.

Returns

boolean

---

headersHidden

headersHidden: boolean = false

A boolean property that determines whether the table headers are hidden.

Remarks

This property can be used to hide the table headers when needed.

Default Value

false

Examples

table.headersHidden = true;

<bim-table headers-hidden></bim-table>

---

indentationInText

indentationInText: boolean = false

A boolean property that determines whether the table indentation should be included in the exported text.

Default Value

false

Example

table.indentationInText = true;

---

loadFunction?

optional loadFunction: TableLoadFunction<T>

The function to be executed when loading async data using Table.loadData

---

preserveStructureOnFilter

preserveStructureOnFilter: boolean = false

A boolean property that determines whether the table preserves its structure when filtering. When true, the table will preserve its structure, showing only the filtered rows and their parents. When false, the table will not preserve its structure, showing only the filtered rows.

Default Value

false

Example

table.preserveStructureOnFilter = true;

---

styles

static styles: CSSResult[]

CSS styles for the component.

Overrides

LitElement.styles

Accessors

columns

set columns(value): void

Sets the columns for the table. This property allows you to define the columns order for the table. If this is not set, it will be computed from the table.data object. The columns can be provided as an array of strings or objects of type ColumnData. If the columns are provided as strings, they will be converted to ColumnData objects with a default width.

Example

const columns: (string | ColumnData)[] = [
  "Column 1",
  "Column 2",
  { name: "Column 3", width: "200px" },
];
table.columns = columns;

Parameters

Parameter	Type	Description
value	(ColumnData<T> | keyof T)[]	An array of strings or objects of type ColumnData.

---

csv

get csv(): string

A getter function that generates a CSV (Comma Separated Values) representation of the table data.

Example

const csvData = table.csv;
console.log(csvData); // Output: "Column 1,Column 2\nValue 1,Value 2\nValue 3,Value 4"

Returns

string

A string containing the CSV representation of the table data.

---

data

set data(value): void

Sets the data for the table. This property allows you to define the data that will be displayed in the table. The data is expected to be an array of TableGroupData objects. If the columns are not explicitly set, they will be computed from the data object.

Example

const data: TableGroupData[] = [
  { data: { "Column 1": "Value 1", "Column 2": "Value 2" } },
  { data: { "Column 1": "Value 3", "Column 2": "Value 4" } },
];
table.data = data;

Parameters

Parameter	Type	Description
value	TableGroupData<T>[]	An array of TableGroupData objects representing the table data.

---

queryString

set queryString(_value): void

Sets the search string for filtering the table data. This property allows you to filter the table data based on a search string. If a search string is provided, the table will only display rows that match the search criteria. The search criteria can be a simple string or a complex query. If a simple string is provided, the table will filter rows based on the string's presence in any column. If a complex query is provided, the table will filter rows based on the query's conditions and values.

Examples

table.queryString = "example";

table.queryString = "column1="Jhon Doe" & column2=20";

Parameters

Parameter	Type
_value	null | string

---

tsv

get tsv(): string

A getter function that generates a Tab Separated Values (TSV) representation of the table data.

Example

const tsvData = table.tsv;
console.log(tsvData); // Output: "Column 1\tColumn 2\nValue 1\tValue 2\nValue 3\tValue 4"

Returns

string

A string containing the TSV representation of the table data.

---

value

get value(): TableGroupData<T>[]

Getter for the value property. Returns the filtered data if a search string is provided, otherwise returns the original data.

Example

const tableValue = table.value;
console.log(tableValue); // Output: The filtered or original data.

Returns

TableGroupData<T>[]

Methods

downloadData()

downloadData(fileName, format): void

The downloadData method is used to download the table data in different formats.

Parameters

Parameter	Type	Default value	Description
fileName	string	"BIM Table Data"	The name of the downloaded file. Default is "BIM Table Data".
format	"json" | "tsv" | "csv"	"json"	The format of the downloaded file. Can be "json", "tsv", or "csv". Default is "json".

Returns

void

• This method does not return any value.

Example

table.downloadData("MyTableData", "tsv");

---

loadData()

loadData(force): Promise<boolean>

Asynchronously loads data into the table based on Table.loadFunction. If the data is already available, just set it in Table.data.

Parameters

Parameter	Type	Default value	Description
force	boolean	false	A boolean indicating whether to force loading even if the table already has data.

Returns

Promise<boolean>

• A promise that resolves to a boolean indicating whether the data loading was successful. If the promise resolves to true, the data loading was successful. If the promise resolves to false, the data loading was not successful.

Remarks

• If the table already has data and force is false, the function resolves to false without making any changes. If the table already has data and force is true, the existing data is discarded before loading the new data. If an error occurs during data loading, the function sets the errorLoadingMessage property with the error message and resolves to false.
