How to configure spreadsheet view?

Watching to the data, I can control the precision or enlarge columns’ widths manually.
But when I step through the instantaneous states of my data, only the precision is kept :frowning:
The width is resized automagically, even in case of enough space in the relevant window …

How to control the format of floats (exponential etc.) used in spreadsheet view?

Many thanks in advance for any hint!
