General ⇒ Read from file

[remusmp]

Hello,

I'd like to ask you whether it's possible or not to read data from file. I would like to build a table with some data that is in a txt file. I know the number of rows, the number of columns, I just need to fill in the table with data from a separate file.

Thanks.

R.

This can be done manually with the \openin, \read and \closein primitives, or, less tediously, with packages like datatool or pgfplotstable.
