The vertical columns in a periodic table are called Groups.
They are called gridlines. These are not to be confused with borders, which are the heavier lines that users can put in with different colours and styles. Gridlines are purely used to clearly show the columns and rows.They are called gridlines.
A matrix in mathematics is a rectangular array of quantities or expressions set out by rows and columns.
The general term is a matrix. But you may be asking about a specific set of information, such as the periodic table?
Using the DISTINCT keyword in the SELECT clause ensures that only one copy of each set of duplicate rows selected is returned. This keyword filters out duplicate rows from the result set based on all selected columns.
In Mathematics, an array is an arrangement of quantities or symbols in rows and columns; a matrix. In Computing, an array is an indexed set of related elements.

Selection: Filters rows in a table based on a specified condition, creating a subset of rows that meet the criteria.

A Table is a set of data elements that are organized using a model of vertical columns and horizontal rows. Cell is the intersection of the column and row.
In information technology / database technology this would be a data table. Conceptually, think of it as a spread sheet. Each row contains a set of columns. The values in the columns usually represent a single instantiation of a entity.
The SQL order allows a result set with rows being sorted by the values of one or more columns. At the present time it is the only known way to sort the rows in the result. It will also prevent the database system fro returning the rows in any order.
