I created a new library to show a table (or grid) similar to the one in EXCEL.
There are already excellent classes that allow many to accomplish things, such as xCustomListView by @Erel (B4X) and with the FlexibleTable by @klaus (B4A). I wanted to make something slightly different suited to my needs.

There are already excellent classes that allow many to accomplish things, such as xCustomListView by @Erel (B4X) and with the FlexibleTable by @klaus (B4A). I wanted to make something slightly different suited to my needs.
WARNING
The use of libraries for personal and / or commercial use is permitted. It is not allowed to modify the sources or change the name of the library. Reverse engineering is not authorized to access the sources for any reason, not even for study or learning reasons.
Explanations:
- To get the calculation of the cells that contain a formula I have added Erel's B4XEval to my Library, but as soon as possible I will make it external so that everyone can modify it according to their needs.
- To select multiple cells, position yourself on the first cell of those to be selected (the one at the top left) click a shot and then click again and drag your finger to cover all the cells (or area) that you want to select
- It is still in beta version, presents problems in large grids.
Now only forB4A and B4iNow for B4A,B4i,B4j- In the example to select a group of cells just long click on a cell (not checkbox). In the case of B4J click with the right mouse button
