How can I deselect one row in JTable?

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?

Try method clearSelection on JTable .
it works by calling clearSelection on the ListSelectionModel

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);

Get all selected rows by shift click

If I have a JTable in java and if I click on the first row then shift+click lets say on the 10th row, how would get all the selected rows between 1 and 10... Is there a code for it? thanks in advance

how would get all the selected rows
Check out the JTable API. You can use the getSelectedRows() method to get the indexes of all the selected rows. Then you write a loop to iterate through the indexes to access the data that you need.

I believe what you're asking for is the method JTable.setSelectionMode(int), using as parameter ListSelectionModel.SINGLE_INTERVAL_SELECTION or possibly ListSelectionModel.MULTIPLE_INTERVAL_SELECTION, to enable the selection of multiple contiguous rows. For instance:
JTable table = ...;
table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

Selecting the Multiple Rows randomly in JTable

Can I select the multiple rows randomly in JTable?
I tried with
table.setRowSelectionInterval(index 0, index 2);
It will select three rows 0,1 and 2, but I need to skip the selection of index 1.
How can I accomplish this?
thanks in advance

There is no way to set a discontinous selection with a single method call, you need at least two:
table.setRowSelectionInterval(0, 0);
table.addRowSelectionInterval(2, 2);

set Jtable properties-
selectionModel- Multiple Interval Selection
The first row selection should be done with setRowSelectionInterval(i,j)
The subsequent row selections (in the same JTable) should be done with addRowSelectionInterval(i,j)
Use
ListSelectionModel selectionModel =
jTable1.getSelectionModel();
selectionModel.setSelectionInterval(1, 1);//for first row selection
selectionModel.addSelectionInterval(3, 3);
selectionModel.addSelectionInterval(5, 5);

How to select only cells in one row in a jtable?

I have a JTable consisting of multiple rows and columns. I want to make the cells selectable, but only in one row at a time. So for example, when I click on the cell in third row and the fifth column, I can pull the mouse to the left or right and select more cells, but only in this specific row and not in the row above or below.
How can I do this?

Use the setSelectionMode() method from ListSelectionModel interface, and set the selection mode to ListSelectionModel.SINGLE_SELECTION.
This will configure JTable to work with one row at a time selection, blocking selection of multiple rows.
To select single cells, combine the above with setColumnSelectionAllowed(true) on TableColumnModel, and you should get what you need.

how to add row values to jtable in java swing?

I have a jcombo box which has some items like "schoolbooks","collegebooks","historybooks".and i have dynamic ArrayList object of corresponding books...When i click the combo box item "schoolbooks" or "historybooks" ,it should display the contents in JTable from the arraylist.while every action performing,the JTable has to display the contents of the corresponding item of 'schoolbooks' or 'historybooks' .it should not append new rows when every action is performing ...i have used default table model in this.but when i add 3 or 4 rows using default table model,its appending the row with previous here..if i use removeRow(i) in for loop ,its removing 1 row or 2 rows only...Its not removing previous all rows suppose if i have 7 rows ..i am not able to solve this..please if anyone know this,please help...

You might want to review How to Use Tables as a guide to preparing your sscce. As you are using DefaultTableModel, you'll need to show how you construct the Object[] passed to addRow() and how you calculate the index passed to removeRow().

if i use removeRow(i) in for loop ,its removing 1 row or 2 rows only...Its not removing previous all rows suppose if i have 7 rows
When you remove multiple rows you need to remove the row from the end of the table down to 0:
for (int i = table.getRowCount() - 1; i > 0; i--)
{
// add logic here
}
