如何取消选择JTable中的一行？

Question

I have JTable with ListSelectionModel.MULTIPLE_INTERVAL_SELECTION:

 table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

When I use CTRL+mouse click, rows are selected and all are right. But if I want to deselect only one selected row and press CTRL+mouse click to one selected row, all rows are deselected, not only one. Then if I press CTRL+mouse click to some row again, previouse rows are selected again, but without row, that I wanted to deselect. I want to deselect only one row using CTRL+mouse click. How can I do that?

EDIT: I had this in my code:

table.getColumnModel().setColumnSelectionAllowed(true);

I found that if I remove this line then all works fine. But can JTable work correctly although 'ColumnSelectionAllowed' is true?

Answer 1

Try method clearSelection on JTable .

it works by calling clearSelection on the ListSelectionModel

Answer 2

If you are looking for deselection one row from many, use the below code:

table.getSelectionModel().removeSelectionInterval(rowFrom, rowTo);

for deselecting one row:

table.getSelectionModel().removeSelectionInterval(row, row);

you can use multiple selection like this

table.getSelectionModel().removeSelectionInterval(1, 3); //1,2,3 starting from 0
table.getSelectionModel().removeSelectionInterval(5, 5); //5

to add it back, use:

table.getSelectionModel().addSelectionInterval(rowFrom, rowTo);

you can use multiple selection like this

table.getSelectionModel().addSelectionInterval(1, 2); //1,2
table.getSelectionModel().addSelectionInterval(4, 4); //4

to set it to specific range, which will clear your old selection first,

table.getSelectionModel().addSelectionInterval(rowFrom, rowTo);

Which it is equal to:

table.clearSelection();
table.getSelectionModel().addSelectionInterval(rowFrom, rowTo);
