shell: combining several tables

Within same workdir I have several 2 column tables (with | separators between the columns) containing the same number of lines and share the order within the first column . Here is an example for two tables containing 8 lines: table 1.csv lig10| -5.4600 lig13| -5.9900 lig14| -4.2200 lig15| -4.9200 lig3| -6.9700 lig4| -7.4000 lig5| -6.0000 lig9| -6.5700 table 2.csv lig10| -5.2400 lig13| -6.6900 lig14| -4.4600 lig15| -4.9600 lig3| -6.9000 lig4| -6.3100 lig5| -3.7900 lig9| -6.5800 I would like to merge all tables in that (quite similar) format together side-by-side into big table, taking all data, so that the resulting table should contain the same number of lines with the number of columns proportional to number of fused filles. E.g. for 10 separate tables it would be 20 column table (note: I always take the column number one, even it is the same for all tables!),etc In the resulting table I would like to add header for each 2nd column (of initial table), according to the name of the initial file. Here is expected output for the 2 tables. Is it possible to use some linux utility to fuse the tables in terminal in one line command like prog -i /workdir/*.csv -o resulting_table.csv
