Question

我使用NetBeans IDE创建了此表。问题是，如果它有超过20行，它只显示那20行。其他行未显示，也不会滚动。

它只显示表格中最后一行的一半（见图）。

我更改了滚动窗格的宽度和高度，并将表格放在另一个滚动窗格中，但这不起作用。

此代码由NetBeans生成。

spStockItems.setAutoscrolls（真）; spStockItems.setMinimumSize（new java.awt.Dimension（452,300））; spStockItems.setPreferredSize（new java.awt.Dimension（452,300））;

    tblStockItems.setFont(new java.awt.Font("Arial", 0, 11)); // NOI18N
    tblStockItems.setModel(new javax.swing.table.DefaultTableModel(
        new Object [][] {

Answer 1

摆脱......

spStockItems.setMinimumSize(new java.awt.Dimension(452, 300));     
spStockItems.setPreferredSize(new java.awt.Dimension(452, 300));

和...

tblStockItems.setMinimumSize(new java.awt.Dimension(452, 300));
tblStockItems.setPreferredSize(new java.awt.Dimension(452, 300));

这些与JScrollPane确定表格何时需要滚动的方式紧密相关。

学习如何使用布局管理器，并且不要害怕在多个组件中使用多个布局来构建UI。

花点时间学习手工编写您的用户界面，它会让您更好地了解它的内容以及表单编辑器的限制（以及何时使用它们）

Java Swing表不会在末尾显示行并且不会滚动
