pdf-table | Java utility for parsing PDF tabular data using Apache | Document Editor library

The reference manual has this to say about the table.move function, introduced in Lua 5.3:

table.move (a1, f, e, t [,a2])

Moves elements from table a1 to table a2, performing the equivalent to the following multiple assignment: a2[t],··· = a1[f],···,a1[e]. The default for a2 is a1. The destination range can overlap with the source range. The number of elements to be moved must fit in a Lua integer.

This description leaves a lot to be desired. I'm hoping for a general, canonical explanation of the function that goes into more detail than the reference manual. (Oddly, I could not find such an explanation anywhere on the web, perhaps because the function is fairly new.)

Particular points I am still confused on after reading the reference manual's explanation a few times:

• When it says "move", that means the items are being removed from their original location, correct? Do the indices of items above the removed items shift down to fill the gaps? If so, and we're moving within the same table, does t point to the original location before anything starts moving?
• Is there some significance to the choice of index letters f, e, and t?
• There is no similar function in any other language I know. What's an example of how I might use this? Since it's one of only seven table functions, I presume it's quite useful.

I have dependencies on org.bytedeco:opencv:4.1.2-1.5.2 that is in turn added to the project by

I recently updated my electronJS app to a higher version together with electron-builder. I have no issues running the app with "npm start", however when I try to build it using electron-builder I get the following error when running "npm run dist":

I just started writing node.js code.

I'm writing a code that extracts data from a pdf file, cleans it up and stores it in a database (using couchdb and accessing that using nano library).

The problem is that the calls are being made asynchronously... so the database get calls (i make some get calls to get a few affiliation files during the clean up) get completed only after the program runs resulting in variables being undefined. is there any way around this?

I've reproduced my code below

I want to export my dataframe to a pdf file. Dataframe is pretty large, so it is causing problems while exporting. I used gridExtra package as specified here writing data frame to pdf table but it did not work for my dataframe as it contains a lot of data.

Any ideas how it can be achieved?

I would like to use R and the Tidyverse to write one (long) statement to read data from a PDF-table and show as animated plot.

What i can't get right is

1. retrieving the table-header
2. and turning the numeric values into a numeric format.

Note that i try this because i want to learn using the Tidyverse-functions. With multiple steps i did succeed (see code below).

I just like to learn if its possible in one continous 'flow'.

Thanks for your advice!

I have a list of pdf files and I want to extract tables from these files. So I use pdf-table-extractor to to this.

If I had only one pdf file, I can use this code:

When I try to use PDF::Table module on Debian Jessie (Perl 5.20), I get this message:

I am using iTextSharp to create a new pdf-file. The pdf will contain one headline and one pdf-table. The file-size of the resultant pdf-file should be as small as possible, so I use the default font (Helvetica, 12pt). Is there a way to change the default-font-size from 12pt to 8pt.

I know that I can set the font for each pdf-table-cell.

But is it possible to set the default-font-size for the whole document/table, so that I don't need to set the font for each and every table-cell extra?

(I googled on this topic, but did not find an answer)
