Latex formula and table recognition

Formula recognition

I found a good thing today , If you want to copy the formulas in other people's articles to your own latex in , You can use the following website
https://www.latexlive.com/home##
After landing , You can take a screenshot directly , Then we can get the corresponding latex Code
for example

Copy the screenshot directly to the online website
You can see that this result is much faster than knocking one by one

With this above , I want to do another thing , Whether there is latex What about the plug-ins that recognize tables ,
I searched it , There is , yes excel2latex La

install excel2latex

Reference resources
https://www.bilibili.com/read/cv14219721/

First go to the official website to download
https://ctan.org/tex-archive/support/excel2latex/
Then open the excel

Get into
Then find the download just now xla file , Click OK to install
If the installation is successful , So the final result is as follows

Use the tutorial

First prepare a excel form , as follows
First select all the data of the table
Then select the corresponding table in the add in , as follows
Here we can generate
Click on Copy to Clipboard You can copy it to the pasteboard , There seems to be an error when saving to a file , But I don't need this either ,
But here's a little bug,

Now copy it latex In fact, the code format is messy , Copy directly to texstudio in

This is too messy , Direct operation will report an error , Value required \begin{table} and \end{table} Change the line before
, Or you can copy the code to typora in , And then from typora Zhongba latex Code copy to texstudio in

Here you can see , The format has changed , Finally, you can run texstudio Look at the results of the table , Here is my test code
