Angular Data Grid: Column API

Below are listed all the column API methods.

Column Keys

Some of the API methods take Column Key (named colKey) which has type Column | string. This means you can pass either a Column object (that you receive from calling one of the other methods) or you pass in the Column ID (which is a string). The Column ID is a property of the column definition. If you do not provide the Column ID, the grid will create one for you (first by trying to use the field if it is unique, otherwise it will generate an ID).

Column Groups

See Column Groups

getColumnGroup
Function
Returns the column group with the given name. See Column Groups.
function getColumnGroup(
    name: string,
    instanceId?: number
): ColumnGroup | null;
getProvidedColumnGroup
Function
Returns the provided column group with the given name. 
function getProvidedColumnGroup(name: string): ProvidedColumnGroup | null;
setColumnGroupOpened
Function
Call this if you want to open or close a column group. 
function setColumnGroupOpened(
    group: ProvidedColumnGroup | string,
    newValue: boolean
): void;

Columns

getColumn
Function
Returns the column with the given colKey, which can either be the colId (a string) or the colDef (an object). 
function getColumn(key: any): Column | null;
getColumns
Function
Returns all the columns, regardless of visible or not. 
function getColumns(): Column[] | null;
getAllGridColumns
Function
Returns all the grid columns, same as getColumns(), except a) it has the order of the columns that are presented in the grid b) it's after the 'pivot' step, so if pivoting, has the value columns for the pivot. 
function getAllGridColumns(): Column[];

Moving

See Column Moving

moveColumn
Function
Moves a column to toIndex. The column is first removed, then added at the toIndex location, thus index locations will change to the right of the column after the removal. 
function moveColumn(
    key: string | Column,
    toIndex: number
): void;
moveColumns

Sizing

See Column Sizing

setColumnWidth
Function
Sets the column width on a single column. The finished flag gets included in the resulting event and not used internally by the grid. The finished flag is intended for dragging, where a dragging action will produce many columnWidth events, so the consumer of events knows when it receives the last event in a stream. The finished parameter is optional, and defaults to true. 
function setColumnWidth(
    key: string | Column,
    newWidth: number,
    finished: boolean = true,
    source?: ColumnEventType
): void;
setColumnWidths
Function
Sets the column widths on multiple columns. This method offers better performance than calling setColumnWidth multiple times. The finished flag gets included in the resulting event and not used internally by the grid. The finished flag is intended for dragging, where a dragging action will produce many columnWidth events, so the consumer of events knows when it receives the last event in a stream. The finished parameter is optional, and defaults to true. 
function setColumnWidths(
    columnWidths: { key: string | Column; newWidth: number; }[],
    finished: boolean = true,
    source?: ColumnEventType
): void;
sizeColumnsToFit
Function
Gets the grid to size the columns to the specified width in pixels, e.g. sizeColumnsToFit(900). To have the grid fit the columns to the grid's width, use the Grid API gridApi.sizeColumnsToFit() instead. 
function sizeColumnsToFit(gridWidth: number): void;

function autoSizeColumn(
    key: string | Column,
    skipHeader?: boolean
): void;

): void;
autoSizeAllColumns
Function
Calls autoSizeColumns on all displayed columns. 
function autoSizeAllColumns(skipHeader?: boolean): void;
