How to lock the layout of cells

Dear LOo community,

Today I created a nicely laid out spreadsheet in Calc, which will be used to cut-and-paste a lot of different data around in. This all works well of course, except that with each cut-and-paste the layout of cells is going with it and as a result the general layout is ‘broken’.
So my question is - how do I lock the layout (specifically border style) of cells so when data is cut out of or paste into the cells, the layout remains? General locking seems to also prevent me from modifying the contents, which should remain modify-able.

You could try to copy and paste special, only pasting the values of the cells instead of all the formatting etc. Then separately delete the content of the original cells.
