public class Column
```

Represents a single column in a worksheet.

**Example**

```
         //Instantiating a Workbook object
         Workbook workbook = new Workbook();
 
         //Obtaining the reference of the first worksheet
         Worksheet worksheet = workbook.getWorksheets().get(0);
         Style style = workbook.createStyle();
 
         //Setting the background color to Blue
         style.setBackgroundColor(Color.getBlue());
 
         //Setting the foreground color to Red
         style.setForegroundColor(Color.getRed());
 
         //setting Background Pattern
         style.setPattern(BackgroundType.DIAGONAL_STRIPE);
 
         //New Style Flag
         StyleFlag styleFlag = new StyleFlag();
 
         //Set All Styles
         styleFlag.setAll(true);
 
         //Get first Column
         Column column = worksheet.getCells().getColumns().get(0);
 
         //Apply Style to first Column
         column.applyStyle(style, styleFlag);
 
         //Saving the Excel file
         workbook.save("book1.xls");

### applyStyle(Style style, StyleFlag flag) {#applyStyle-com.aspose.cells.Style-com.aspose.cells.StyleFlag-}
```
public void applyStyle(Style style, StyleFlag flag)
```


Applies formats for a whole column.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| style | [Style](../../com.aspose.cells/style) | The style object which will be applied. |
| flag | [StyleFlag](../../com.aspose.cells/styleflag) | Flags which indicates applied formatting properties. |

### equals(Object arg0) {#equals-java.lang.Object-}
```
public boolean equals(Object arg0)
```




**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| arg0 | java.lang.Object |  |

**Returns:**
boolean
### getClass() {#getClass--}
```
public final native Class<?> getClass()
```




**Returns:**
java.lang.Class<?>
### getGroupLevel() {#getGroupLevel--}
```
public byte getGroupLevel()
```


Gets the group level of the column.

**Returns:**
byte
### getIndex() {#getIndex--}
```
public int getIndex()
```


Gets the index of this column.

**Returns:**
int
### getStyle() {#getStyle--}
```
public Style getStyle()
```


Gets the style of this column.

**Remarks**

Modifying the returned style object directly takes no effect for this column or any cells in this column. You have to call [applyStyle(Style,StyleFlag)](../../com.aspose.cells/column\#applyStyle-Style-StyleFlag-) or [setStyle(Style)](../../com.aspose.cells/column\#setStyle-Style-) method to apply the change to this column.

Column's style is the style which will be inherited by cells in this column(those cells that have no custom style settings, such as existing cells that have not been set style explicitly, or those that have not been instantiated)

**Returns:**
[Style](../../com.aspose.cells/style)
### getWidth() {#getWidth--}
```
public double getWidth()
```


Gets the column width in unit of characters.

**Remarks**

For spreadsheet, column width is measured as the number of characters of the maximum digit width of the numbers 0~9 as rendered in the normal style's font.

**Returns:**
double
### hasCustomStyle() {#hasCustomStyle--}
```
public boolean hasCustomStyle()
```


Indicates whether this column has custom style settings(different from the default one inherited from workbook).
