However, if data is a DataFrame, then data['a'] returns all values in the column(s) named a. To avoid this ambiguity, Pandas supports the syntax data.loc['a'] as an alternative way to filter using the index. Pandas also supports the syntax data.iloc[n], which always takes an integer n and returns the nth value, counting from 0. This allows a ...
Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record.
header cell Optional. Each header cell starts with a new line and a single exclamation mark (!), or several header cells can be placed consecutively on the same line, separated by double exclamation marks (!!). |-new row To begin a new row of cells, use a single vertical bar (|) and a hyphen (-). | new cell in row
MediaWiki’s wikitable class (class="wikitable") is designed for straightforward table formatting and enforces certain global styles that make removing borders between adjacent cells challenging even if custom CSS styles attempt to eliminate these borders. Specifically, the class includes:
The class plainrowheaders will apply left-aligned and normal-weight formatting so that editors do not feel the need to override the header formatting with inline CSS declarations for each cell. [note 3] Used by itself, plainrowheaders will make headers appear similar to unmodified data cells, except for the darker background.
This leads to interoperability problems with library headers which use, for example, #pragma pack(8), if the project packing is smaller than this. For this reason, setting the project packing to any value other than the default of 8 bytes would break the #pragma pack directives used in library headers and result in binary incompatibilities ...
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.

Header fields are colon-separated key-value pairs in clear-text string format, terminated by a carriage return (CR) and line feed (LF) character sequence. The end of the header section is indicated by an empty field line, resulting in the transmission of two consecutive CR-LF pairs.
