我知道table.getColumn("字段").setCellRenderer(new ButtonRenderer())可以设置某一列的Renderer
但如何设置JTable某一个cell的Renderer

给你个例子：
thisRenderer = new DefaultTableCellRenderer() {

public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected,
boolean hasFocus, int row,
int column)
{
if (column ==0){File thisfile=new File(((File)value).getName());
return super.getTableCellRendererComponent(table, (File)thisfile, isSelected,
hasFocus, row,
column);

}

else
{

JButton bn=new JButton("button");
return bn;
}}

使用 AbstractTableModel 构建Table 在表格中添加JButton按钮，之前在网上找了2天没有找到好用的程序，最终终于找到一个好用的例子。不要使，我退你们分。。 sing the Swing JTable class can quickly become a sticky business when you want to customize it to your specific needs. First you must become familiar with how the JTable class is organized. Individual cells are rendered by TableCellRenderer implementations. The table contents are represented by an implementation of the TableModel interface. By default, JTable uses DefaultTableCellRenderer to draw its cells. DefaultTableCellRenderer recognizes a few primitive types, rendering them as strings, and can even display Boolean types as checkboxes. But it defaults to displaying the value returned by toString() for types it does not specifically handle. You have to provide your own TableCellRenderer implementation if you want to display buttons in a JTable. The TableCellRenderer interface contains only one method, getTableCellRendererComponent(...), which returns a java.awt.Component that knows how to draw the contents of a specific cell. Usually, getTableCellRendererComponent() will return the same component for every cell of a column, to avoid the unnecessary use of extra memory. But when the contents of a cell is itself a component, it is all right to return that component as the renderer. Therefore, the first step towards having JButtons display correctly in a JTable is to create a TableCellRenderer implementation that returns the JButton contained in the cell being rendered. In the accompanying code listing, JTableButtonRenderer demonstrates how to do this. Even after creating a custom TableCellRenderer, you're still not done. The TableModel associated with a given JTable does not only keep track of the contents of each cell, but it also keeps track of the class of data stored in each column. DefaultTableModel is designed to work with DefaultTableCellRenderer and will return java.lang.String.class for columns containing data types that it does not specifically handle. The exact method that does this is getColumnClass(int column). Your second step is to create a TableModel implementation that returns JButton.class for cells that contain JButtons. JTableButtonModel shows one way to do this. It just returns the result of getClass() for each piece of cell data. At this point, you're almost done, but not quite. What's the use of putting a JButton in a JTable if you can't press the darn thing? By default, JTable will not forward mouse events to components contained in its cells. If you want to be able to press the buttons you add to JTable, you have to create your own MouseListener that forwards events to the JButton cells. JTableButtonMouseListener demonstrates how you could do this.

尝试Swing已经一星期，感觉Swing里的坑还是很多的，对于我这种刚入门的新手来说，接口确实有些不顺手。闲话休提。需求是这样的，绘制一个数据表格，假如其中某个单元格的数据超出阈值，该单元格标红。在Swing的库里简略地翻了一阵子的结果是，并没有找到现成的、设置单个单元格的接口，

下面这个实例是设置表格的第一行第三格背景颜色为蓝色，前景颜色为红色。 package com.test.view; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Component; import javax.swing.JFrame; import javax.swing.JScrol
