 The key to always remember is that double quotes recognize and interpret escapes so if you have any `\` characters in your string, they will be interpreted as escapes. The following is an example of a question we get frequently on Discord.
 
 ```nu

+# => Why doesn't this work?
+cd "C:\Program Files\somedir"

 It doesn't work because it sees `\P` and `\s` as escapes that are not recognized.

 Table literals can be created using a syntax similar to that of a list literal. Because tables also contain columns and not just values, we also specify the column names:

 You can also create a table as a list of records, JSON-style:

 This list-of-records pattern plays on the Nushell data model, which sees a list of records as equivalent to a table. This is useful in cases where the length of a table may not be known ahead of time. In such a case, a stream of records likewise represents a table.
