### Getting Started with Tables

Entering tables is easy depending on what type of data you're looking to represent. To add a blank table, open the Add Item menu and choose Table. You can also type 'table' in a blank expression line.

Enter values into the table and use the arrow keys to easily maneuver through the table. Click on the zoom fit icon to automatically adjust the axis settings to fit the data.

### Scatter Plots

You can also copy and paste data from an existing spreadsheet. Desmos will automatically generate a table.

Note: The column header titles will not transfer and there is a maximum of 1000 rows that are able to be copy and pasted in a table.

Now that you have a scatterplot, how about finding a line of best fit? Learn more about regressions in Desmos.

### Externally Define Columns in a Table

You can now externally define any column in a table (including the first column).

Explore externally defined table columns in Desmos. Change the values in the list \(L\) and watch how the table changes.

### Function Tables

Columns of tables at Desmos.com have different behaviors depending on their headings. If you put a function of x in the 2nd header, we'll fill it in as a function table, calculating the values for you. For example, if you have "\(x_1\)" and "\(sin (x_1)\)" as your headings, we'll fill in the 2nd column for any point you put in the first.

You can write rich math expressions in the cells, including things like \(\frac{\pi}{2}\).

To compare two functions side by side, add another column and enter another function into the new heading.

You can define a function in an expression line and use it in your table to evaluate based on your \(x\) values.

### Create a Table from a Function

Expressions and points can be shown as tables using 'Create Table.' To start, click the Edit List button. If the expression line contains an available expression, a Create Table button will appear. Click on it to add a table of values that match the expression line.

Equations, expressions, points, and lists of points can be converted to a table.
