tablemodel

问题 There is JTable with the following content Col1 | Col2 A | 1 A | 2 A | 3 B | 5 B | 1 C | 5 C | 4 C | 2 Based on this table, I need to create a HashMap numbers : column 1 refers to keys and column 2 refers to data. Below I provide my code snippet. The question is: is there any quicker way to create the mentioned HashMap? HashMap numbers = new HashMap<String, List<String>>(); for (int i=0; i<tbNumbers.getRowCount(); i++) { col1 = mdNumbers.getValueAt(i,0).toString(); col2Array = new ArrayList

问题 My jtable is loaded with data and this is where I call my Pop up functionality on jTable. jTable.addMouseListener(new TablePopupListener(jTable)); displayTable(); So basically, if I right click a row, a popup(credit check) comes up and if I click it is setting a value to the last cell in that row. Now, based on this column cell value I have to define the color of a row. Let's say, if the cell value is fail then turn the row to red else to green. I have tried customCellRenderer and defined my

问题 I'm removing a row in my JTable and i have this Exception : IndexOutOfBoundsException: Index: 1, Size: 1".

问题 UPDATE : I found this answer by @MadProgrammer and it worked! Updating JTable on button click Basically, you add a refresh() method to your TableModel that takes in the updated Object. Then, every time the button is pressed, this method of the tablemodel is called. I assume that you can also extend JTable and put this method inside the extended class. There might be more efficient solutions, but I will stick for this one for now. Thank you! /***************************************************
