In this java tutorial you will learn how to set the height and width of rows and columns in JTable. Earlier, you have read about the JTable that contains the data in rows and columns format so, each and every rows and columns have some specific height and width for containing the data. JTable provides some specified height and width for the table. Whenever you want to store the larger data in it, you will have to increase it, after that you can store the data in it that will look clearly.
Description of program:
In this program we are going to set the height and width of rows and columns in JTable. This table has multiple data but some data are longer for this we must require for setting its height and width by using the setPreferredWidth() and setRowHeight(). The setPerferredWidth method helps us for setting the column width and setRowHeight method is used to set the rows height. These methods are used to set the height and width of all rows and columns but if you want to set the specific rows and columns then you must maintain its index of rows and column. See the example:-
Code of program:
This is the class that represents all descriptions of a column in a JTable like: width, maximum and minimum width, resizable. It provides the multiple slots to a renderer and an editor that is used for displaying and editing the values in the column.
Above method contains all columns information of a specified table and returns the TableColumnModel object.
This method takes integer type value (index of column of a table) that will match on those table's column index and returns the TableColumn object.
This is the method that set the column width according to specification. It takes integer type value. Whenever, you entered the value minimum or maximum of its limiting value, it will adjust to an appropriate limiting value.
This method is used for setting the height in pixels of all rows of a table. It takes integer type value to set each rows of the table depending upon it.
row_height: It denotes rows height of a table.
setRowHeight(int row_index, int row_height):
This method sets the row's height of specific row that takes two arguments e.g:
row_index: It is an integer
value that represents the index
of rows that works for modifying the row.
row_height: It is an integer value that represents the height of rows that works for modifying the height in the row.
Here is the code of program:
