"Every table must be called out in the text in sequential order. For example, Table 3 should not be called out before Table 1—this will require the copyeditor to renumber the tables and move them. All callouts must match the tables provided" (ASCE 2019)
Table labels and titles are placed above the table. Titles are formatted in sentence case.
Title: Table titles begin with the boldface “Table,” followed by a boldface Arabic number and a period.
Example: Table 1. Ultimate rotations at the joint interfaces and beam ends
All columns must have a heading. Each table should have only one set of column headings at the top of the table. Using additional column headings within the body of the table should be avoided.

Just like tables, figures are also called out in the text in sequential order.
Figure labels and titles are placed below the figure. Figure titles are formatted in sentence case.
"Figure captions should be short and to the point; they need not include a complete explanation of the figure. Each caption should begin with the abbreviation “Fig.” followed by an Arabic number, followed by a period:
Fig. 1. Plan view.
Fig. 2. Percentage breakdown of practitioner responses: Year 1 and Year 2." (ASCE 2019)
Calling out tables and figures means that in the text of the document—sometimes referred to as the body or narrative of a report—the author(s) specifically mention(s) the table or figure that is being described or referred to in that sentence.
