(v-table &
         {:keys [model virtual? row-height row-viewport-width
                 row-viewport-height max-row-viewport-height src]
          :or {virtual? true}
          :as args})

Renders a scrollable table with optional fixed column and row headers and footers, totalling nine addressable sections By default, it only displays rows that are visible, so is very efficient for large data structures The table supports click+drag selections within the rows section (5), row header section (2) and col header section (4)

The table is laid out using an h-box for the outer component, with four v-box 'container sections' sitting next to each other:

+-----+---------+-----+-+ | | | | | | | | | | | | | | | |LEFT | MIDDLE |RIGHT|VS | | | | | | | | | | | | | | | |- - -|- - - - -|- - -|-| +-----+---HS----+-----+-+

The four 'container section' v-boxes are named:

• LEFT: contains the row headers (and corresponding two corner sections)
• MIDDLE: contains the main content area (the rows), along with column headers and footers and the horizontal scrollbar (HS)
• RIGHT: contains the row footers (and corresponding two corner sections)
• VS: contains the vertical scrollbar

Each container section holds 'sections' which are numbered:

+-----+---------+-----+ | 1 | 4 | 7 | +-----+---------+-----+-+ | | | | | | 2 | 5 | 8 |VS | | | | | +-----+---------+-----+ + | 3 | 6 | 9 | +-----+---------+-----+ +---HS----+

The nine 'sections' are named:

• 1: top-left
• 2: row-headers
• 3: bottom-left
• 4: column-headers
• 5: rows
• 6: column-footers
• 7: top-right
• 8: row-footers
• 9: bottom-right

The corner sections (1, 3, 7, 9) are fixed (i.e. do not scroll) and consist of a single 'content' area

The other sections are scrollable: (2, 8) vertical, (4, 6) horizontal and (5) vertical & horizontal as a 'viewport' onto their (potentially larger) 'content' area

Arguments:

• model [mandatory atom containing vector of maps (or other data structures)] The data to be displayed, consisting of rows. Each row is normally a map but could be anything) Rows MUST contain a unique id (specified via :key-fn arg) They are passed to the row-renderer (section 5), row-header-renderer (section 2) and row-footer-renderer (section 8) NOTE: data for sections 1, 3, 4, 6, 7 and 9 are not included in model

• key-fn [optional fn or keyword to extract a unique id from the row data, or not specified/nil to indicate that v-table should use the internally generated 0-based row-id] A row is passed to key-fn and it returns the unique identifier for that row

• virtual? [optional bool, default = true] When true, use virtual feature where only a screen-full (viewport) of rows are rendered at any one time Use true for tables with many rows to reduce initialisation time and resource usage You can use false for smaller tables to improve performance of vertical scrolling

• remove-empty-row-space? [optional bool, default = true] Specifies whether to remove empty row space (the space between the last row and the horizontal scrollbar) for small tables that don't fill the space available to the v-table This will cause the horizontal scrollbar section to be nestled against the last row, and whatever is underneath the v-table to be brought up with it

• max-width [optional string, default = nil (table will fill available space)] MAXIMUM width of the entire v-table NOTE: This is specified as a normal CSS value, e.g. "1024px" or "90%"
