JTable problems, Resizing and Editing

[fatcodeguy]

Hi, I have a JTable with two columns, and it's the only component on a JTabbedPane. The records in one column are small, and in another large, but the title for each column is just a word. How do I set the size of a column, and have the other take the rest of the space. The other problem, is how do I set the table for no editing. Thanks

Is the JTable set directly into the JTabbedPane, or do you set it into a JPanel, and then the JTabbedPane - this may affect issues ...

You could try something like this for setting the column sizes:

for(int id = 0; id < 2; id++)
{
column = tableName.getColumnModel().getColumn(id);
switch(id)
{
case 0: column.setPreferredWidth(10); break;
case 1: column.setPreferredWidth(30); break;
}
}

or you could just set the size of the first column and use:
tableName.setAutoResizeMode(JTable.AUTO_RESIZE_LAST_COLUMN);

For no editing you could try:
tableName.setCellSelectionEnabled(false);
or something like:
tableName.setColumnSelectionAllowed(false);
tableName.setRowSelectionAllowed(false);

This might be useful to you:

for preventing editing on a table :

In your TableModel to the isCellEditable method add return false;

public MyTableModel extends AbstractTabelModel{
public boolean isCellEditable(int iRow, int iCol){
return false;
}
}
this will prevent the table from editing
