Class ColumnCollection

java.lang.Object

com.aspose.cells.CollectionBase

com.aspose.cells.ColumnCollection

All Implemented Interfaces:

java.lang.Iterable

public class ColumnCollection
extends CollectionBase

Collection of the Column objects that represent the individual column(setting)s in a worksheet. The Column object only represents the settings such as column width, styles, .etc. for the whole column, has nothing to do with the fact that there are non-empty cells(data) or not in corresponding column. And the "Count" of this collection only represents the count Column objects that have been instantiated in this collection, has nothing to do with the fact that there are non-empty cells(data) or not in the worksheet.

Example

 
         //Instantiating a Workbook object
         Workbook workbook = new Workbook();
 
         //Obtaining the reference of the first worksheet
         Worksheet worksheet = workbook.getWorksheets().get(0);
 
         //Add new Style to Workbook
         Style style = workbook.createStyle();
 
         //Setting the background color to Blue
         style.setForegroundColor(Color.getBlue());
 
         //setting Background Pattern
         style.setPattern(BackgroundType.SOLID);
 
         //New Style Flag
         StyleFlag styleFlag = new StyleFlag();
 
         //Set All Styles
         styleFlag.setAll(true);
 
         //Change the default width of first ten columns
         for (int i = 0; i ᝺ i++)
         {
             worksheet.getCells().getColumns().get(i).setWidth(20);
         }
 
         //Get the Column with non default formatting
         ColumnCollection columns = worksheet.getCells().getColumns();
 
         for (Column column : (Iterable<Column>) columns)
         {
             //Apply Style to first ten Columns
             column.applyStyle(style, styleFlag);
         }
 
         //Saving the Excel file
         workbook.save("book1.xls");
