请问如何改变(设置)JTable对象的第i列列宽？

[alphazhao]

我通过扩展AbstractTableModel，通过提供getRowCount,getColumnCount，getValueAt三个方法，利用数据库查询的结果集ResultSet，将查询数据库的结果用一个JTable显示出来。
现在问题来了，我想问一下JTable有没有方法可以设置第i列的列宽？
我找了找帮助，硬是没有找倒……
惨
哪位兄台可以帮我啊？

javax.swing.table.TableColumnModel tcm = jTable1.getColumnModel();
javax.swing.table.TableColumn tc =tcm.getColumn(1);
tc.setPreferredWidth(130);

or also can automatically adjust the columan size for differnt table header and content,

[soldier1002]

public class MyTableModel extends AbstractTableModel{
Object[][] data;
String[] columnNames;
public MyTableModel(Object[][] tableData, String[] inColumnNames){
data = tableData;
columnNames = inColumnNames;
}

public Object getValueAt(int row, int col){
return data[row][col];
}

public Class getColumnClass(int c){
return getValueAt(0, c).getClass();
}

public int getColumnCount(){
return data[0].length;
}
public int getRowCount(){
return data.length;
}
public String getColumnName(int col){
return columnNames[col];
}

public boolean isCellEditable(int row, int col){
if(col == 2){
return true;
}else{
return false;
}
}
public void setValueAt(Object value, int row, int col){
data[row][col] = value;
fireTableCellUpdated(row, col);
}
}

[Apocalypse]

table.getColumn("column name").setMinWidth(width);
table.getColumn("column name").setMaxWidth(width);
table.setColumnsToFit(0); //据说是JTable的bug，必须如此调用

[soldier1002]

and use the following fuction to automatically adjust


private void initColumnSizes(JTable table, MyTableModel model, Object[][] tableData){
TableColumn column = null;
int headerWidth = 0;
int cellWidth = 0;

//resize the first columan size to feet
for(int i = 0; i<1; i++){
column = table.getColumnModel().getColumn(i);
String colName = tmodel.getColumnName(i);
JTextField t = new JTextField(colName);
headerWidth = new Double((t.getPreferredSize().getWidth())).intValue();
for(int j =0; j<tableData.length ; j++){
t = new JTextField(tableData[j][i].toString());
cellWidth = Math.max(cellWidth, t.getPreferredSize().width);
}
column.setPreferredWidth(Math.max(headerWidth, cellWidth));
}
}
