board.java

package com.diesal11;  import javax.swing.jpanel; import javax.swing.jtable;  public class board extends jpanel{      private static final long serialversionuid = 1l;      tetris parent;     int boardwidth = 10;     int boardheight = 20;     jtable table;      public board(tetris parent){ //      setfocusable(true);         this.parent = parent;         this.table = new jtable(this.boardwidth, this.boardheight);         this.table.setvalueat("aaa", 0, 0);         this.table.setautoresizemode(jtable.auto_resize_off);         this.table.getcolumnmodel().getcolumn(1).setheadervalue("test");     } }

thanks in advance! im new java apologies if it's simple!

you should add table jpanel:

    ....     this.table.setautoresizemode(jtable.auto_resize_off);     this.table.getcolumnmodel().getcolumn(1).setheadervalue("test");     this.add(table);

also, convention start variable names lower case letter.
