Property Details
context
The request context associated with the object. This connects the add-in's process to the Office host application's process.
context: RequestContext;Property Value
items
Gets the loaded child items in this collection.
readonly items: Word.TableColumn[];Property Value
Method Details
		add(beforeColumn)
	 
	Returns a TableColumn object that represents a column added to a table.
add(beforeColumn?: Word.TableColumn): Word.TableColumn;Parameters
- beforeColumn
- Word.TableColumn
Optional. The column before which the new column is added.
Returns
A new TableColumn object.
Remarks
		autoFit()
	 
	Changes the width of a table column to accommodate the width of the text without changing the way text wraps in the cells.
autoFit(): void;Returns
void
Remarks
delete()
		distributeWidth()
	 
	Adjusts the width of the specified columns so that they are equal.
distributeWidth(): void;Returns
void
Remarks
load(options)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(options?: Word.Interfaces.TableColumnCollectionLoadOptions & Word.Interfaces.CollectionLoadOptions): Word.TableColumnCollection;Parameters
Provides options for which properties of the object to load.
Returns
		load(propertyNames)
	 
	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames?: string | string[]): Word.TableColumnCollection;Parameters
- propertyNames
- 
				string | string[] 
A comma-delimited string or an array of strings that specify the properties to load.
Returns
		load(propertyNamesAndPaths)
	   
	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths?: OfficeExtension.LoadOption): Word.TableColumnCollection;Parameters
- propertyNamesAndPaths
- OfficeExtension.LoadOption
propertyNamesAndPaths.select is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand is a comma-delimited string that specifies the navigation properties to load.
Returns
select()
Selects the specified table columns.
select(): void;Returns
void
Remarks
		setWidth(columnWidth, rulerStyle)
	   
	Sets the width of columns in a table.
setWidth(columnWidth: number, rulerStyle: Word.RulerStyle): void;Parameters
- columnWidth
- 
				number 
The width to set.
- rulerStyle
- Word.RulerStyle
The ruler style to apply.
Returns
void
Remarks
		setWidth(columnWidth, rulerStyle)
	   
	Sets the width of columns in a table.
setWidth(columnWidth: number, rulerStyle: "None" | "Proportional" | "FirstColumn" | "SameWidth"): void;Parameters
- columnWidth
- 
				number 
The width to set.
- rulerStyle
- 
				"None" | "Proportional" | "FirstColumn" | "SameWidth" 
The ruler style to apply.
Returns
void
Remarks
toJSON()
Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that's passed to it.) Whereas the original Word.TableColumnCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.TableColumnCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
toJSON(): Word.Interfaces.TableColumnCollectionData;Returns
track()
Track the object for automatic adjustment based on surrounding changes in the document. This call is a shorthand for context.trackedObjects.add(thisObject). If you're using this object across .sync calls and outside the sequential execution of a ".run" batch, and get an "InvalidObjectPath" error when setting a property or invoking a method on the object, you need to add the object to the tracked object collection when the object was first created. If this object is part of a collection, you should also track the parent collection.
track(): Word.TableColumnCollection;Returns
untrack()
Release the memory associated with this object, if it has previously been tracked. This call is shorthand for context.trackedObjects.remove(thisObject). Having many tracked objects slows down the host application, so please remember to free any objects you add, once you're done using them. You'll need to call context.sync() before the memory release takes effect.
untrack(): Word.TableColumnCollection;
