swing - getRowHeight() in java method -

i dont understand how implement method in table class

import javax.swing.table.abstracttablemodel;  public class tabel extends abstracttablemodel{     object columnnames[];     object rowdata[][];     public tabel(object[][] rowdata2, object[] columnnames2) {         rowdata=rowdata2;          columnnames=columnnames2;      }   @override public int getcolumncount() {     return columnnames.length; } public int getrowcount() {     return rowdata.length; }  @override public object getvalueat(int rowindex, int columnindex) {     return rowdata[rowindex][columnindex]; }  public void setvaloare(object value,int row ,int col) {      rowdata[row][col]=value;     firetablecellupdated(row,col);   }  public int getrowheight() {   }  public void changeheight(int row,int column) {      int i=rowdata.length;        }  } 

i don't return because if write return rowdata.height; doesn't work need make method changes height of specific row , column

you don't implement getrowheight() in tablemodel. tablemodel stores data , not know how data rendered.

i need make method changes heigth of specific row

if want change height of specific row can use method jtable:

table.setrowheight(row, height); 

and column

you can't change height of specific column. height of columns given row same.
