Answer 1

Trường có thể tự động kéo giãn với tràn, nhưng nó sẽ bị hỏng (thay đổi từ) thay vì tăng chiều rộng. Trong tài liệu PDF tùy chọn mà bạn tìm kiếm, sẽ có ít hoặc không sử dụng.

Kiểm tra chủ đề này khác để biết thêm Dynamic column cell width

EDIT Ngoài ra kiểm tra và bao gồm JasperReports phông chữ mở rộng. Có lẽ nó có thể giúp đỡ trên một triển khai hoàn hảo mà không có vấn đề phông chữ hệ điều hành.

Answer 2

Có giải pháp. Đã sửa đổi tất cả các trường văn bản tĩnh và tất cả các thuộc tính của phần tử thành positionType = "Float".

Answer 3

Chỉ cần thêm isStretchWithOverflow="true" vào textField mà bạn muốn làm phần tử.

<textField isStretchWithOverflow="true"> 
    <reportElement x="279" y="7" width="202" height="13"/> 
    <textElement/> 
    <textFieldExpression class="java.lang.String"><![CDATA[$F{name}]]></textFieldExpression> 
</textField>
