Hi, Kim.

If i understood, you wish to somehow edit multiple cells at the same time,

and to increase all the numeric values by 50 percent of their original value?

Sorry to disappoint you, but at this time, it is only possible to edit one cell at a time with our plugin.

-

The only way to edit multiple cells at the same time, is if you have a Manual Table,

then if you switch to Excel-Like Editor, you can select a range of cells, and set same value on them,

but I suppose this will not be ideal for your use-case.

If you wish to see a better solution for this in the future,

Please feel free to search on our suggestions page, 

 to see if someone may be already suggested this feature. If you can't see it, feel free to add your suggestion there,  and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like ( it is also available in the plugin dashboard), where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

Other than that, you can only try to somehow use some kind of calculation on your source data,

for example if you use an SQL based table, such as Manual Table,

if you manage to do this on a CSV/Excel or Google Sheet,

then you can update your data source of a Manual Table by uploading the updated file. ( more on updating Manual Table by file upload here).
