JTable Cell Data - java

I am facing a problem with JTable cell data in Java (Swing based application),
In each cell of JTable if I entered any data it is automatically appending to old data,
instead of that I want new data every time in that cell is just like Excel sheet Cell
(For example in Excel sheet when ever we want enter some data in a cell, at that moment old data of the cell is eraised and it allow new data ) my problem is simillar to that only
Advanced Thanks

From kleopatra's link, there is another link: http://tips4java.wordpress.com/2008/10/20/table-select-all-editor/
The code in there will select the content of the cell, you can modify the code to delete the contents instead of select.

You should make a TableModel then add rows of data to your table model. There is plenty of information here https://docs.oracle.com/javase/tutorial/uiswing/components/table.html

Droplist in Excel using Poi

How can I create a drop list in excel like drop list in html with the inbuilt "value" like attribute?
My Requirement is: I want to show the description which is not stored in database, but the code for description.
Ex: I have a subject list in an excel cell, for Science the description is "Science", but I want to store the code "SCI" in the Database.
You could use an ActiveX ComboBox in a worksheet, available from the Developers tab.
Enter both columns of data into the worksheet - you can hide the columns. Then set properties of the combobox:
ColumnCount 2
BoundColumn 1
ColumnWidths 0 pt; 20 pt
Set the ListFillRange and LinkedCell.
I understand there used to be issues with distributing workbooks containing ActiveX controls. I am not sure if this is still an issue, particularly when used a common (standard) control.
Of course, Excel is not designed to be a front-end to a database, so you'll need to write all the code to keep everything in-sync.
You could use the simpler Form Control/ComboBox. This will only store the index number in a cell - it does not have any events that you can use. You could use a formula based on the linked cell, that stores the description in another cell. When the user (presumably) clicks a button to submit the data, you would retrieve and store the description from this cell.
Hmm I can see many placeholder occurs all around the web related to java poi... but it seems there is no solution for your question. The only way I found to manage this is to set the cell value with my default text - the first value!

Apache POI excel cell style update

Using Apache Poi I'm exporting my table to an excel sheet. I extended ExcelExport class, override the getCellStyle method and customized my cell styles.
Now what i want is when a user edits any cell in the excel document i want that cell to change its color, so anyone later reviewing the document can easily see what has been changed.
Is there way to achieve this?
One solution could be to add conditional formatting to the cells use Apache POI's HSSFSheetConditionalFormatting.
For example, if the cell value written by your program is 5 then your conditional formatting could set the cell background to yellow if the value wasn't equal to 5
