Does anybody know how to remove a row from a JTABLE?

[Bala Hari]

To remove a row from a Jtable use the flg. method
yourJTable.removeRow(rownum);

I think you need to use DefaultTableModel for adding and removing rows. Your code might be something like this:
String[] mycolumns = {"column 1 title", "column 2 title"};
String[][] mydata = {{"foo", "bar"}, {"aaa", "bbb"}};
DefaultTableModel mytableModel = new DefaultTableModel(mydata, mycolumns);
JTable mytable = new JTable(mytableModel);
JScrollPane myscrollpane = new JScrollPane(mytable);
// ... somehwere later, whenever you want to remove a row...
int rowNumber = 0;
mytableModel.removeRow(rowNumber); // remove the first row

Need a bit more help on this JTable please...
Is there any way to set the widths of the colums? So if I wanted the first colum to start up twice the width of the second (without manually having to drag it), how would I do that?
Thanks.

You'll need to mess with the TableColumnModel.

First, get the TableColumnModel.

TableColumnModel colModel = [I]tableName[/I].getColumnModel();

Then, get the width of the first column.

int col1Width = colModel.getColumn( 0 ).getWidth();

Then, set the width of the second column.

colModel.getColumn( 1 ).setMinWidth( col1Width * 2 );

And you're done!
