EXCEL TABLES A Table is a structured range of related data formatted to enable data management and analysis Excel tables offer many features not available to regular ranges

TABLE DESIGN A field is an individual piece of data –Field names appear in the top row as column headings –Field names should be short, but descriptive –Each column represents a field A record is a complete set of data for an entity –Each record is listed in a row of the table –Do not insert blank rows in the table –Each record has something unique about it

MANAGING TABLES Create table Delete and add fields Add, Edit and Delete records Remove the duplicates Apply a table style Convert a table to range

SORTING DATA Excel allows you to sort a spreadsheet by alphabetical or numerical or chronological order. Records can be sorted in ascending or descending order Sorting arranges records in a table –Sort on one column –Sort on multiple columns

SORTING BY ONE COLUMN Excel offers several ways to sort a single column Data typeOptionsExplanation TextSort A to ZArranges data in alphabetical order. Sort Z to AArranges data in reverse alphabetical order. DatesSort Oldest to Newest Displays data in chronological order. Sort Newest to Oldest Displays data in reverse chronological order. ValuesSort Smallest to Largest Arranges values in sequential order. Sort Largest to Smallest Arranges values in descending order.

SORTING BY MULTIPLE COLUMNS Multiple level sorts permits differentiation among records with duplicate data in the first sort

CREATING A CUSTOM SORT A custom sort can be created to arrange values in a customized fashion

FILTERING DATA Filtering is the process of displaying only records that meet specific conditions  Apply text filters  Apply number filters  Apply date filters  Apply custom filter  Clear filters

STRUCTURED REFERENCE It is a tag or use of a table element such as a field heading, as a reference in the formula. These are similar to the formulae that we discussed earlier. Can be used only inside a table They always start with [

SHEET REFERENCES You can reference data from another sheet just like you can reference data from your current sheet. Flip to the new sheet in the file For example, In cell B1 type =AVERAGE( For entering the Range Switch to the previous sheet and select a range and hit enter while you are on the same sheet Then cell B1 in new sheet should become =AVERAGE(’Employee Info’!D2:D10) Repeat the same process for Total Salaries

TOTAL ROW A total row appears as the last row of a table to display summary statistics, such as Sum, Max, Min, Average etc.

LOCKING /UNLOCKING A WORKSHEET If a worksheet is “protected”, meaning that the locking property is on, then all cells are locked and no data can be entered. Locking a worksheet –Home ribbon -> Cells group -> Format Cells -> Protect sheet… –Enter a password (twice) –Click OK Unlocking –Home ribbon -> Cells group -> Format Cells -> Unprotect sheet…
