Java 表格格式化

Question

我正在使用 Netbeans 使用 Java 进行编程。

我有一张列出患者的表格。我读取了 XML 文件中的信息。 这里有代码：

package digiscope;

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.io.File;

/**

public class TabelaPaciente extends javax.swing.JPanel {


 String numero_processo;
    int localizador = 0;

    /** Creates new form TabelaPaciente */

    public TabelaPaciente() {
        initComponents();
        load_table();
    }

    public void setNumeroProc(String numero) {
        numero_processo = numero;
    }

    public String getNumeroProc() {
        return numero_processo;
    }

    public int getLocalizador() {
        return localizador;
    }

    String[][] concat(String[][] A, String[][] B) {
        String[][] C = new String[A.length + B.length][A.length + B.length];
        System.arraycopy(A, 0, C, 0, A.length);
        System.arraycopy(B, 0, C, A.length, B.length);

        return C;
    }

    private void load_table() {

        File dir;
        String[] filenames;

        //dir = new File(System.getProperty("user.dir")+ "/XML");
        dir = new File(System.getProperty("user.dir") + "/Processos");

        filenames = dir.list();

        String[][] table_final = new String[][]{};

        for (int i = 0; i < filenames.length; i++) {

            String n_proc = filenames[i];//filenames[i].substring(0,filenames[i].length()-4);

            //System.out.println(filenames[i]);

            Ler_XML xml = new Ler_XML(n_proc);
            String nome_utente = xml.getNome();

            String[][] line = new String[][]{
                {n_proc, nome_utente, null, "ir para formulario"}
            };

            table_final = concat(table_final, line);
        }

        tabela_pacientes.setModel(new javax.swing.table.DefaultTableModel(
                table_final,
                new String[]{
                    "Process Nº", "Name", "Date", "Form state"
                }));
    }



    void executa_accao(int column, int row) {

        if (column == 3) {
            Object numero_proc = tabela_pacientes.getValueAt(row, 0);

            localizador = 1;

            numero_processo = numero_proc.toString();

            JanelaPrincipal cont = (JanelaPrincipal) this.getParent() //    Internal Pane
                    .getParent() // ???
                    .getParent() // ???
                    .getParent() // ???
                    .getParent();   //  Frame

            cont.loadPanel(new Formulario(1));

            Preencher_FormPaciente new_xml = new Preencher_FormPaciente(numero_processo, 1);

        }

    }

我想知道是否可以增加字母大小？ 您可以在此处查看表格的预览。

感谢您的合作。

此致。

Answer 1

在许多情况下，一个表将使用多个呈现器来呈现数据。一种用于字符串、数字、日期等。默认渲染器使用表格的字体来渲染文本。要更改所有渲染器的字体，您可以使用：

Font font = table.getFont();
table.setFont( font.deriveFont(24.0f) );
table.setRowHeight(24);

您也可以对表标题执行此操作。

Answer 2

JTable 中单元格的显示由 TableCell渲染器。 默认 实现从 JLabel 扩展而来，有控制字体的方法。例如...

DefaultTableCellRenderer newRenderer = new DefaultTableCellRenderer();
Font oldFont = newRenderer.getFont();
Font bigFont = new Font(oldFont.getName(),oldFont.getStyle(),24);
newRenderer.setFont(bigFont);
table.setDefaultRenderer(Object.class,newRenderer);
