SQL Optimization: how many columns on a table?

Question

The current project that I\'m working on have table with 126 columns and the least that i saw is at least 50 columns. Should a table hold less columns per table or separate

Answer 1

Columns in a table1 (merge publication) 246

Columns in a table2 (SQL Server snapshot or transactional publication) 1,000

Columns in a table2 (Oracle snapshot or transactional publication) 995

in a table, we can have maximum 246 column
