A table cell is one grouping within a chart table used for storing information or data. Cells are grouped horizontally (rows of cells) and vertically (columns of cells). Each cell contains information relating to the combination of the row and column headings it is collinear with.
In most implementations, a cell, or group of cells in a column or row, can be "named" enabling the user to refer to those cells by a name rather than by a grid reference. Names must be unique within the spreadsheet, but when using multiple sheets in a spreadsheet file, an identically named cell range on each sheet can be used if it is ...
Note that with row headers you need to use a separate row in the wikitext for the row header cell. Here below is what a table looks like if the data cell wikitext is on the same line as the row header wikitext. Note that the data cell text is bolded, and the data cell backgrounds are the same shade of gray as the column and row headers.
a column name can consist of a word, phrase or a numerical index; the intersection of a row and a column is called a cell. The elements of a table may be grouped, segmented, or arranged in many different ways, and even nested recursively. Additionally, a table may include metadata, annotations, a header, [6] a footer or other ancillary features ...
In a database, a table is a collection of related data organized in table format; consisting of columns and rows.. In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect.

In the real world, data modeling is critical because as the data grows voluminous, tables linked by keys must be used to speed up programmed retrieval of data. If a data model is poorly crafted, even a computer applications system with just a million records will give the end-users unacceptable response time delays.
In relational databases, the information schema (information_schema) is an ANSI-standard set of read-only views that provide information about all of the tables, views, columns, and procedures in a database. [1] It can be used as a source of the information that some databases make available through non-standard commands, such as:
A linked list is a sequence of nodes that contain two fields: data (an integer value here as an example) and a link to the next node. The last node is linked to a terminator used to signify the end of the list. In computer science, a linked list is a linear collection of data elements whose order is not given by their physical placement in memory.
