[REBORN !] TableView Extension Versions 3&4 (pre nb191) and 5 by @Ken

[Ela]

thanks, I corrected but still nothing happens, ...all other blocks are correct?

[Taifun]

this

is also incorrect
to debug this, display the list, which is returned by the AppPermissionList method in a label to find out, if you have to use WRITE_EXTERNAL_STORAGE or something else
it also might work together with the orange helper block

@Taifun

orange helper block

where can I find it?
It should replace the block with "WriteExternalStorage"?

[Taifun]

@Ela

where can I find it?

you can find it in the Screen drawer, see also

Testing the next release of MIT App Inventor (nb187)

thank you... this is a great release! I especially like the new dropdowns by @BeksOmega ... I was just looking at the new Permission dropdown... don't we need only the dangerous permissions, which are used by App Inventor components? See a list of all dangerous permissions here https://stackoverflow.com/a/36937109/1545993 Here is a comparison of the permissions... The permissions marked with a red cross are not dangerous, i.e. also not required to list in the dropdown? [Unbenannt] These 8…

but first you should find out

Dear Taifun
I appreciate your answer, but this doesn't help me export my table.
I am aware that I have no competence in this branch of knowledge, even if I try my best to understand all these new words and concepts, and keep finding simple solutions to be able to carry out my project that I've already created in my mind
So I opened another topic: "What is the exact combination of blocks to export the table as an image or PDF?"
Thank you

[Taifun]

let's come back to your previous question

@Ela

I would also like to export the table as an image and save it both in the gallery and share it via email or whatsapp.

just store the image in shared storage and you do not have to ask for write permission...
see also the overview

Some basics on Android storage system

I have added another detail to my overview (top right, see pink box) and thus completed the overview. ( I hope. ) [grafik]

you might want to post the latest screenshot of your relevant blocks

PS: @Ela 's thread continues here

What is the exact combination of blocks to export the table as an image or PDF?

Hi I have already read various topics and guides on export methods such as: creating sheets in Google Sheets - is a rather complicated method that I cannot propose to the users of my app. I also don't need to change the data once it's exported. as PDF - would be the best format because it automatically splits into A4 sheets ready to be printed, but from what I have read it seems there are various problems and limitations (need of multiple screens, only works for androi…

I would be more than happy to help Robinson but I am on vacation on a remote island in Pacific right now and no PC. Here is an example of how I made use of Ken's extension. I also used a few row/column as selection buttons.

hello

How can I view the data in a table with this extension whose source is the csv file is hosted in a cloud or dropbox?

@Djibril_BINGA

How can I view the data in a table with this extension whose source is the csv file is hosted in a cloud or dropbox

1. Download the csv file to your app
2. Read the csv file with the File component
3. Set the file contents to a csv table
4. Import the csv table data to the tableview extension (TableView1.DataString)
5. Build the Table

Wes_Savage, muchas gracias por su voluntad de ayudar a los demas.

At runtime, if I update values for an existing Table, how do I clear or delete the table before updating? Currently, the update gets appended to the existing.

[TIMAI2]

Should be just a case of update the list, then using the setDataString block and the buildTable block ?

[ChrisWard]

Tried that, the rows get appended to existing.

[ChrisWard]

I have also tried setting the data to text nothing + build, and resetting the colour of the vertical array.

[ChrisWard]

You simply can't delete or overwrite the table data string .... unless there is a specific character to use. I've tried data = "", data = " ", data = "0". They are ignored and the original data is retained.

If items of data are modified, the modifications are all there, but all the rows are appended to the existing rows. Running out of screen ink.

EDIT: The magic character to clear the table is '\n'

[TIMAI2]

How are you going about updating a value in the table / list ?

[ChrisWard]

Companion, editing test data.

[ChrisWard]

..also tested as an APK.

I was thinking that being able to flush the TableView DataString would be enough to allow for runtime modifications/updates (think sensor values and switch/relay statuses arriving every minute or Users typing in updates or simply modifying data because the input was wrong, followed by a re-draw of the Table).

I wonder how the Table is rendered. Is it effectively an HTML page that can be deleted from the display? Given that the selected row can be highlighted and cell/row text queried, plus all the presentation refinements available, it must be something like that.

Edit: Fixed in v4

[ChrisWard]

Is there a concrete way to align the text in the columns? By default they align center but for example a decimal (float) column needs to be aligned right and often the first column is text, which would want align right too.

...ah, set the font to monospace and pad with space chars?

Edit - no, it doesn't like monospace

[Mohamed_Salama]

thanks .. can you describe how can use the scrolltorow options ...?
