constructor(DeleteOptions)
Constructs from a parent object convertible to this.
constructor(obj: DeleteOptions);
Parameters:
| Parameter | Type | Description |
|---|---|---|
| obj | DeleteOptions | The parent object. |

setEmptyStringAsBlank(value: boolean) : void;
Parameters:
| Parameter | Type | Description |

getEmptyFormulaValueAsBlank()
Whether one cell will be taken as blank when it is formula and the calculated result is null or empty string. Default value is false.
getEmptyFormulaValueAsBlank() : boolean;
Remarks
Generally user should make sure the formulas have been calculated before deleting operation with this property as true. Otherwise all newly cretaed formulas by normal apis such as Cell.Formula will be taken as blank and may be deleted because before calculation their calculated results are all null.
setEmptyFormulaValueAsBlank(boolean)
Whether one cell will be taken as blank when it is formula and the calculated result is null or empty string. Default value is false.
setEmptyFormulaValueAsBlank(value: boolean) : void;
Parameters:
| Parameter | Type | Description |

getDrawingsAsBlank() : boolean;
Remarks
When setting this property as false, all rows/columns covered by drawing objects will not be taken as blank and will not be deleted.
setDrawingsAsBlank(boolean)
Whether drawing related objects such as picture, shape, chart… will be taken as blank. Default value is true.

Parameters:
| Parameter | Type | Description |
|---|---|---|
| value | boolean | The value to set. |
Remarks

getMergedCellsShrinkType()
Indicates how to process merged cells when deleting blank rows/columns.
getMergedCellsShrinkType() : MergedCellsShrinkType;
Returns
Remarks
