      Get Column/Row   
      
         The class Column/Row represents the column/row of table.To get all the columns or rows you can use the getColumnList or getRowList of the table instance. 
      
 
      
      
        
	List <Column > columns = table.getColumnList(); 
	List <Row > rows = table.getRowList(); 
 
        
      
      
         You can also get single column/row by specifying the index of the column/row. 
      
 
      
         The column/row index start from 0.If not found, null will be returned. 
      
 
      
      
        
	 
	Column  column = table.getColumnByIndex(2); 
	Row  row = table.getRowByIndex(0); 
 
        
      
      
         If you want to know the count of header column/row in the table,you can do like this: 
      
 
      
      
        
	int  headerColumnCount = table.getHeaderColumnCount(); 
	int  headerRowCount = table.getHeaderRowCount(); 
 
        
      
      
         If you want to know the index of the column/row,you can use the method below: 
      
 
      
      
        
	int  columnIndex=column.getColumnIndex(); 
	int  rowIndex=row.getRowIndex(); 
 
        
      
      
         Can I get the previous or next Column/Row by the current column/row instance? 
      
 
      
         Yes,you can ask the column/row instance itself,if it doesn't exist,null will be returned. 
      
 
      
      
        
	Column  previousCol=column.getPreviousColumn(); 
	Column  nextCol=column.getNextColumn(); 
	Row  previousRow=row.getPreviousRow(); 
	Row  nextRow=row.getNextRow(); 
 
        
      
      
      Append or Insert Column/Row   
      
         You can add a column to the end or insert many columns before the specified index 
      
 
      
         The appendColumn/Row method add an empty column/row at the end and return the new appended column/row 
      
 
      
      
        
	Column  newColumn=table.appendColumn(); 
	Row  newRow=table.appendRow(); 
 
        
      
      
         What can I do if I want to insert a column/row into the specified position? 
      
 
      
         You can use the insertColumn/RowBefore method,whose first parameter is the index of the column/row to be inserted before; The second parameter is the number of columns/rows to be inserted. 
      
 
      
      
        
	List <Column > cols = table.insertColumnsBefore(1, 2); 
	List <Row > newRows = table.insertRowsBefore(0, 2); 
 
        
      
      
      Remove Columns/Rows   
      
         You can delete a number of columns/rows by index 
      
 
      
         The first parameter is the index of the first column/row to delete; The second parameter is the number of columns/rows to delete. 
      
 
      
         The code below remove 1 column whose index is 2;remove 2 rows whose index is 1,2. 
      
 
      
      
        
	table.removeColumnsByIndex(2, 1); 
	table.removeRowsByIndex(1, 2); 
 
        
      
      
      Set Column/Row   
      
         If you want to change the width of the column or the height of the row,you can use it like this: 
      
 
      
         If the second parameter of row's setHeight is true, the row can fit the height to the text, vice versa. 
      
 
      
      
        
	column.setWidth(column.getWidth()/2); 
	row.setHeight(row.getHeight()/2, true );
