update values of changed cells into database using
I have to design a page which looks like a metrics i.e. in the column part it has all the headers like PLExplanation, Date, BookName1, BookName2, BookName3, BookName4 etc. listed and in the row part it is having the row number. now the intersecting cell will contain the datas. Upon Clicking that cell, user will be presented with a Menuwindow in which he can select the options like Edit or Audit. In the menuwindow when you select edit option, the cell becomes editable and the user can change the value. But, it should not update immediately into the database but it should store that value for that cell temporarily and when user presses finally the Submit button all the values stored into these table cells should be updated. But the catch here is, only those cell values which are changed should be updated, not all the cell values.
