The Table Window and Tables Node
The Table window displays the results from integral and variable evaluations defined in Derived Values nodes or by probes and stored in Table nodes. It can also display results from nodes under Evaluation Group nodes as an Evaluation Group window (see About Evaluation Groups).
See Table for information about the Settings window.
A Tables subbranch () is found under the Results main branch and contains all tables defined in the model. Table nodes can also result from evaluating Derived Values. When you select a Table node to display, the window name changes to the name of the Table (Table 1, as in Figure 21-4, for example).
For Windows users, from the Home toolbar, select Windows>Table.

You can control the default values for new tables on the Results page in the Preferences dialog box for the following table properties: maximum number of rows, maximum filled matrix size, and display precision.
Table Window toolbar and Menu Options
When a Table () is generated and displays in the Table window, a variety of editing options are available as listed in Table 21-8 and shown in Figure 21-4. For the different notation options, only one of them can be selected. Likewise, only one of the two forms for displaying complex-valued numbers can be selected, and those forms are only applicable if the table contains some complex-valued numbers with nonzero imaginary part.
The scientific notation, such as 3.1416E-5, can be easier to read than decimal notation for tables containing values on different scales.
The engineering notation, such as 31.416E-6, is similar to scientific notation but with the powers of ten as multiples of three.
The decimal notation uses only decimal representation of the numbers, such as 0.000031416. Small numbers can get long representations because of leading zeros, and large numbers may appear with excess precision.
Click to plot the table as a Table Graph plot in the Graphics window.
For tables with filled data, click to plot the table as a Table Surface plot in the Graphics window.
Click to export the table to a text file in a spreadsheet format or to a Microsoft Excel Workbook (*.xlsx) if the license includes LiveLink™ for Excel®. When saving to a Microsoft Excel Workbook, an Excel Save dialog box opens where you can specify the sheet and range and whether to overwrite existing data and include a header.
