JTable Multiple Header Rows

由 人盡茶涼 提交于 2019-11-27 04:32:37
I am using a JTable in my application and wish to have 2 rows for headings, similar to this: Is this even possible or will I have to do something else? If so, what? Using Supertitle-titleA, SuperTitle-titleB will take up too much space and make information redundant. We had the same requirement in our last project. What I have found is an Implementation for a GroupableTableHeader on java2s.com . However, I have pimped it a bit, although I cannot recall what exactly. Beneath is the implementation of the three classes as how we use them. ColumnGroup.java import java.awt.Component; import java

I searched a lot and got some answers for this Q. but many of them referred to links which give 404 error. I want to make table like this: Is there any method in java for this? MultiSpanCellTableExample demonstrates how to merge cells by creating a custom TableUI . There seem to be a problem in this example that causes StackOverflowError , at least in Java 6. To fix this, inside AttributiveCellTableModel.setDataVector() replace: setColumnIdentifiers(columnNames); with: this.columnIdentifiers = columnNames; IE: public void setDataVector(Vector newData, Vector columnNames) { if (newData == null)

JTable Right Align Header

由 徘徊边缘 提交于 2019-11-26 20:42:26
Basically, I have a JTable containing columns with right-aligned cells but left-aligned headers which looks really bad. I would like to right-align the headers of these columns without altering the "Look and Feel" of the headers. Thanks Here's an alternate approach to modifying the TableCellRenderer of a table's JTableHeader . It's not strictly necessary for this usage, but it minimizes the impact on the UI delegate's appearance. Typical usage: JTable table = new JTable(…); JTableHeader header = table.getTableHeader(); header.setDefaultRenderer(new HeaderRenderer(table)); Custom header

How can I put a control in the JTableHeader of a JTable?

由 一个人想着一个人 提交于 2019-11-25 21:55:34
问题 Given a JTable with a column of type Boolean.class , the default renderer is a JCheckBox . It\'s easy enough to select individual cells based on a user selection, but it may be convenient to select all or none of the check boxes, too. These recent examples mentioned using JCheckBox in the table header, but the implementation was awkward and unappealing. If I don\'t need to sort the column, how can I put a well-behaved control in the JTableHeader? Addendum: For convenience, I\'ve added my
