Autonumbering table caption with multiple digits

Hi community,

I am working in an InDD book. There are four "chapters" have a series of tables that I'd like to auto-number.

I need help figuring out how to do it for multiple digits (Table 1.1.1). A few things to keep in mind:

-Each "chapter" is not named "chapter 1, chapter 2," nor is it autonumbered

-Within each "chapter," there are several subsections with tables that require numbering with three digits (the digits do not correspond to chapter/subheading numbering, so they cannot be pulled/associated with them)

As an example, in the first "chapter," tables will be numbered as follows

Ch 1 First section:

Table 1.1.1
Table 1.1.2

Table 1.1.3

Ch 1 Second section:

Table 1.2.1

Table 1.2.2

Table 1.2.3

Ch 2 First section:

Table 2.1.1

Table 2.1.2

Table 2.1.3

Ch 2 Second section:

Table 2.2.1

Table 2.2.2

Table 2.2.3

In the past, I've created separate paragraph styles for eaach of the sections. So for example, per the screenshot below, updating the number field acrross differrent paragraph styles to progress from 1.1.# to 1.2.#.

Is this the fastest/easiest way to do this? Or, is there a simple way via a single paragraph style where I can auto-generate the second and third digits? I've found if I use table 1.^#.^#, it does the following with my captions:

Table 1.1.1

Table 1.2.2

Table 1.3.3

When I want it to read:

Table 1.1.1

Table 1.1.2

Table 1.1.3

With the second character only increasing when I get to the next section:

Table 1.2.1

Table 1.2.2

Table 1.2.3
