One of the finest effects of this property and value
is in the display of very large sets of tabular data.
Not only does it allow a more precise control over
column behavior, it also makes possible the instant
display of the first table rows while the rest of
the table is still loading.
Without it, you have the default behavior of Web
browsers, in which no part of the table is displayed
until the *whole* table is downloaded and parsed once
for each level of nesting.
With this style on a table, the user gets the illusion
of a much faster download and is able to read data
