Note, rowspan="2" and colspan="2" can be used on cells to span multiple rows and columns. Header cells are created with ! Header cell, which can be column or row headers. Data cells are created with | Data cell. A new column can be added by adding another cell to the first row.
For more complex table structures, Visual editor offers cell-merging operations; see details here.. In addition, it is usually possible to add or import a table that exists elsewhere (e.g., in a spreadsheet, on another website) directly into the visual editor by:
Edit-tricks are most useful when multiple tables must be changed, then the time needed to develop complex edit-patterns can be applied to each table. For each table, insert an alpha-prefix on each column (making each row-token "|-" to sort as column zero, like prefix "Row124col00"), then sort into a new file, and then de-prefix the column entries.
To do so with multiple columns click the top left non-column-header cell, and then shift-click the bottom right cell. When you click on "ascending" or "descending" in the data menu the table will be sorted alphabetically. That is the default. Paste that sorted table (or just the selected columns of interest) directly into the visual editor.
It is possible to create tables with cells that stretch over two or more columns or rows (also known as merged cells). For columns, one uses |colspan=n | content, whereas for rows, one uses |rowspan=m | content. In the table code, one must leave out the cells that are covered by such a span. The resulting column- and row-counting must fit.
The two most commonly used classes are "wikitable" and "wikitable sortable"; the latter allows the reader to sort the table by clicking on the header cell of any column. caption Required for accessibility purposes on data tables, and placed only between the table start and the first table row.
There is a way to break up a table (a too-wide table for example) into more tables without losing all the background colors, and other inline styling. Copy the table to 2 sandboxes (or one sandbox, and in the article itself). Then delete the columns not needed on one of the new tables.
If you create a sortable table or change one to be sortable, you need to understand the software's logic when sorting. First, the software decides which of four types of data is in that column: dates, currency, numbers, or text (what Wikipedia calls strings). Looking down the column, the software finds the first non-blank cell and assumes that ...
