Hi Trang,
Watch your terminology.
Pages do not exist until it comes to printing.
Worksheets (sheets) are what you see on the tabs at the bottom
you could have other sheets besides worksheets.
Workbook is the filename.
Borders and Gridlines are not the same.
Gridlines are 1 pixel wide and you can have them visible or not
you can have them print or not. Interior color will wipe out the
surrounding gridlines.
If you want to put borders on all cells in your current (activesheet) you
would select all cells (ctrl+A, except in Excel 2003) then
format, cells, borders, choose color, choose each border.
If you want to do the same for all sheets in the workbook then
right click on the worksheet tab, select all sheets
.... do the same as in previous paragraph...
Must ungroup the sheets as any change to the visible worksheet
will also be done to the other sheets in the group, and would destroy
the content of your workbook very quickly.
right click on worksheet tab, UNGROUP sheets
If you want to make this so that all future workbooks have borders
to start with you would create a book.xlt in your XLSTART directory
and if you want to add any more sheets to any existing or future workbooks
you would create a sheet.xlt worksheet as your default.
