[JAVA] How do I set or change JTable column width?

private JScrollPane getExceptionDBTable(){ // ScrollPane for Table JScrollPane mExceptionListScroll = new JScrollPane(); // Table final JTable mTable = new JTable(); mTable.setBackground(Color.WHITE); mTable.setFillsViewportHeight(true); mTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); mTable.setBackground(Color.WHITE); mExceptionListScroll.setViewportView(mTable); mExceptionListScroll.setBounds(10, 5, 752, 108); mExceptionListScroll.setBackground(Color.WHITE); // Model for Table DefaultTableModel mTableModel = new DefaultTableModel() { private static final long serialVersionUID = 1L; public Class<?> getColumnClass(int column) { switch (column) { case 0: return Boolean.class; case 1: return String.class; case 2: return String.class; case 3: return String.class; case 4: return String.class; default: return String.class; } } }; mTableModel.addColumn(" "); mTableModel.addColumn("Path"); mTableModel.addColumn("Type"); mTableModel.addColumn("Module"); mTableModel.addColumn("Time"); // Data Row for (int i = 0; i <= 10; i++) { mTableModel.addRow(new Object[0]); mTableModel.setValueAt(false, i, 0); mTableModel.setValueAt("/storage/sdcard0/mtklog/aee_exp/db.0" + (i+1), i, 1); mTableModel.setValueAt("Externel EE" + i, i, 2); mTableModel.setValueAt("md" + i, i, 3); mTableModel.setValueAt("Wed Feb 25 15:21:0" + i, i, 4); } mTable.setModel(mTableModel); // Defines table's column width. int[] columnsWidth = { 50, 150, 100, 150, 150 }; // Configures table's column width. int i = 0; for (int width : columnsWidth) { TableColumn column = mTable.getColumnModel().getColumn(i++); column.setMinWidth(width); column.setMaxWidth(width); column.setPreferredWidth(width); } return mExceptionListScroll; }

아래 Code가 JTable에서 칼럼 폭을 설정해 주는 것입니다.

[How do I set or change JTable column width?]

    // Defines table's column width.

    int[] columnsWidth = {

            50, 150, 100, 150, 150

    };

        

    // Configures table's column width.

    int i = 0;

    for (int width : columnsWidth) {

        TableColumn column = mTable.getColumnModel().getColumn(i++);

        column.setMinWidth(width);

        column.setMaxWidth(width);

        column.setPreferredWidth(width);

    }

단, 주의점은 setMaxWidth를 설정해주게 되면, 그 이상으로 사이즈 조절이 불가능합니다.
