Tables

In Liii STEM, matrices, aligned formula , etc., can all be regarded as "tables" ( Inserting a table by pressing Alt + t in math mode, it can be transformed into matrices, determinants, etc. by Tab cycling).

TableInsertion and Reference Methods are detailed in Cross-Referencing.

You learn further in mastering the usage of tables, matrix and piecewise functions in this guide.

1. Types of Tables

Ordinary tables, a type of table without numbering and captions. It is categorized by its width, alignment, and the presence of labels and borders.

Numbered tables, a type of table with numbering and captions. A big tableoccupies a singleline while a small table doesn't.

2. Table Editing

Insert Table: Click the insert a table button in the mode toolbar (as shown below) and select the table type.

Add/Del Rows & Cols: A new table starts as a single empty cell. When the table is selected, its controls will appear in the focus (current environment) toolbar.

From left to right, are: insert row above, insert column to the left, insert column to the right, and insert row below; the last four are the corresponding deletion operations.

Tip： Use Magic Paste on any AI-generated table to get a ready-to-go version in one click.

3. Table Basics

Click the →Table properties in the focus (current environment) toolbar to openTable Properties.

Or right-click after selecting the table to bring up the function bar .

• Set Table Size

You can set the number of rows and columns in four ways.

**a.**Settle from the focus (current environment) toolbar .

b. Set "Rows" and "Columns" in the Table Properties window.

**c.**Right click to bring up the function bar, then set it in Table → Size.

d. Use the shortcut Alt+Arrows.

Additionally, you can also set min/max row and column counts for the table, which helps in building custom table macros.

Note: Any row/column property set outside the permitted min/max range will be ignored, and the current property will remain unchanged.

• Width and Height Adjustment

You can set the table's overall width and height in Table Properties or the function bar. Two common sizing strategies are:

1. Wide Table: In the Function Bar Width→ Paragraph, it will fill up the Paragraph after adjustment.

2. Inline table: In the function bar Width→ Automatic, the size will be automatically determined by the contentafter adjustment.

• Split Page

For long tables presented across pages, you can click Enable page breaking in Table Properties to enable page breaking.

Note: If the cell is a block, it is recommended to set the line/paragraph spacing of this paragraph to 0 to avoid extra whitespace at the page break.

4. Applications in Mathematics

Matrices are presented in the form of tables in Liii STEM: you can add or delete rows and columns, set alignment and dimensions just like editing a table, and then select the outer delimiters (parentheses, square brackets, vertical bars, etc.).

Thus, most table editing methods are equally applicable to matrices.

• Matrix

Click Insert math→Single line/Inline Formula.

In math mode, click on the focus (current environment) toolbar Insert table → Matrix. Then we have a 1x1 empty matrix in the formula line.

Alternatively, use shortcuts:

In math mode, press Alt + T (generates a table) + Tab (turn into matrix), and turn it into determinants, Bmatrices, piecewise functions, stacked subscripts by Tab cycling.

Rows and columns can also be added via Alt + Arrows.

• Piecewise Function

A piecewise function is essentially a table with a left-side brace. We can edit it in the same way as in a table:

a. In math mode, use the \choice command to insert a brace and a single-column table. Or use the shortcut Alt+t to generate a table and turn it into a piecewise function by Tab cycling.

b. Use Alt + Arrows to add columns or rows.

**c.**Manually input the function, equal signs, and other components.
