        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.
